the NCoC refers to only having several tickets for the single train jouney
That's not right. The relevant part of the NcoC states
National Rail Conditions of Carriage said:
C. USE OF TICKETS
19.
Using a combination of tickets
You may use two or more tickets for one journey as long as together they cover the entire journey and one of the following applies:
(a) they are both Zonal Tickets (unless special conditions prohibit their use);
(b) the train you are in calls at a station where you change from one
ticket to another; or (c) one of the tickets is a Season Ticket (which for this purpose does not include Season Tickets or travel passes issued on behalf of a passenger transport executive or local authority) or a leisure travel pass, and the other ticket(s) is/are not.

To interpret
one journey as limited to
a single train is not sustainable because this interpretation conflicts with other parts of the NCoC. For example, the rules for break of journey
National Conditions of Carriage said:
C. USE OF TICKETS
16. Starting, breaking or ending a journey at intermediate stations
You may start, or break and resume, a journey (in either direction in the case of a return ticket) at any intermediate station, as long as the ticket you hold is valid for the trains you want to use. You may also end your journey (in either direction in the case of a return ticket) before the destination shown on the ticket. However, these rights may not apply to some types of tickets for which a break of journey is prohibited, in which case the relevant Train Companies will make this clear in their notices and other publications.
make no sense if a
journey is limited to travel on one train only. It is plain, therefore, that a
journey may be undertaken using a combination of tickets on several trains.
It is your responsibility to present yourself in time to catch your booked train if travelling on Advance Tickets
That's not quite right either. The Conditions of Use of Advance Tickets say
Advance ticket terms and conditions said:
Conditions of use
* You must be at the departure station shown on your ticket in good time to catch the train. If you miss the first train on which you are booked for any reason, a new ticket must be purchased.
* If delays occur while travelling, you will be allowed to take the next available train(s) to complete your journey.

Journey is not defined in the Advance ticket terms and conditions, and therefore takes the same meaning as in the National Rail Conditions of Carriage. In addition, the Advance ticket terms and conditions introduce the term
valid travel itinerary:
Advance ticket terms and conditions said:
When and where the ticket can be used
If the Route also states and Connections, travel is allowed on appropriate connecting trains where shown on the ticket(s) or other valid travel itinerary.
The term
valid travel itinerary is not defined in any railway rules, regulations, terms or conditions in the public domain, therefore these words bear their normal meaning in the English language. It is plain, therefore, that a passenger travelling with an Advance ticket where the route states and Connections may travel in accordance with any
valid travel itinerary they hold, for example a printout of the confirmation of their internet booking. The
valid travel itinerary may involve one or more tickets for zero, one or more trains, zero, one or more buses and any other form of public transport, eg. ship, which is shown on the itinerary to be part of the journey. Rail replacement buses may be included and would be treated as trains for these purposes.
PlusBus tickets would also be part of the journey if shown on the
valid travel itinerary because on the back of each
PlusBus ticket is printed the words
Travel is subject to National Rail Conditions of Carriage (NRCoC). In each case, the passenger benefits from the condition
If delays occur while travelling, you will be allowed to take the next available train(s) to complete your journey.
If you choose not to book through from start to finish, it is you who accept the risk of serious delay.
A pasenger with valid ticket(s) and a
valid travel itinerary benefits, in case of delay, from the protections stated in the ticket terms and conditions.
Why should a TOC take the risk when you're not paying the second TOC a fare that allows for 'open' travel?
The train company must
take the risk because the terms of their franchise or licence require them to operate in accordance with the National Rail Conditions of Carriage.
