There is no guarantee that you will be able to get a quota on the train from Reading to Paddington at that time and indeed the quota available on GWR may push up the through fare more than the quota available on LNER.So it cheaper to split up a journey like Reading to York for example.
If you are traveling on a 10am train from Kings Cross, the fare from Reading into London Will be more than the advance from Kings Cross
PAYG helps with this as it is priced on a single leg basis.
However, I'd imagine that the numbers of passengers on the 10am from Kings Cross who have come from Reading is dwarfed by those from nearer to London for whom the cost of getting to Kings Cross is less than the increment on a through fare.
The problem appears to be the timeline gap between the introduction of PAYG over a wider area and the desire to abolish CCST tickets. If the extension of PAYG had happened sooner, TfL could have opted out of accepting through fares beyond that area and relied solely on Oyster / Contactless at its stations (which is clearly what they would like) with passengers rebooting as appropriate. TfL are kind of caught in between the acceptance of e-tickets, operating stations well outside of their usual area and a massive desire to standardise on Oyster and Contactless.There is no excuse for TfL not to install e readers at it's NR stations.
If you see the problem from TfL's side, once PAYG is extended, travelcards as we know them are abolished in favour of capping and potentially through tickets are no longer issued for underground travel, spending money on barcode readers, with slower throughput of passengers, isn't a good use of scarce funding.
