We do ask that codes are defined the first time they are used (I'm familiar with these codes already but not everyone is!).
For the record the ticket was Elstree & Borehamwood to Luton airport (bus) and you broke your journey at St Albans [City].
It is often the case that valid tickets do not work barriers; some barriers will reject all tickets of a particular type (not necessarily all tickets of the same name but it may be all tickets with a particular code).
Some train companies make more of an effort than others when it comes to programming their ticket gates.
Gates have no real intelligence and can only have only relatively simple rules defined; rejection of a ticket would not necessarily indicate the ticket isn't valid.

As Yorkie has said, there is not enough space on the magnetic stripes of a ticket to contain all the stations at which a ticket is valid to enter/exit. Ticket barriers do not contain very advanced computers, so more or less they have to be 'spoonfed' what tickets are valid and where.
As a result, it is entirely possible for a ticket barrier to reject a valid ticket (known as a a Type I error), in the same way it is possible for a ticket barrier to accept an invalid ticket (a Type II error).

I wonder if anyone has missed a train due to then having to seek assistance?
Is there really much of a demand for BoJ outside of the enthusiast community? I imagine that most non specialists assume that NR tickets operate in the same way as tube or bus tickets.
Nearly. My ALR didn't work the gates at Wembley Central at circa 0415 one morning and the chump on duty had gone and hid in the office across the concourse with the gates left closed. Made the 0421 to Euston with seconds to spare. That said, I had bags of time until my Eurostar and would have just used the Nightbus if he hadn't eventually sauntered out without a care in the world, despite me telling him that the train was approaching and I wanted to catch it.
Almost - made several Northern/XC trains by seconds - the Virgin redjackets at Manchester Piccadilly have an annoying habit of standing around chatting to one another at times, ignoring half of the gateline.
Cue a fight through a wall of muppets with several suitcases to get over to the manned gate.

The data about wether a ticket is valid for break of journey shouldn't be on the mag strip, it'll be in the gating logic. It all depends on how good the gate programming is.
