Would you expect:
London Terminals to Kemble to allow Moorgate to Paddington;

No I would not.

Oxford to London Terminals to allow Paddington to Moorgate?

No I would not. You will now go and do a test run and come up with
results that differ from my expectation.

I did so. On the way out, London Terminals to Kemble was rejected at
Moorgate, but accepted at Paddington - Lawn gates. On the return trip,
Oxford to London Terminals was swallowed by the gates at Paddington NR,
platforms 2/3 and my opportunity to experiment vanished.


The whole issue here is whether the LU gate is set to be "London
Terminals" plus whether the ticket is encoded via travel via Zone 1.
It's a long time since I did detailed coding stuff but in both of your
examples you will not be able to exit at the LUL destination station as
Zone 1 is not encoded. It's possible the gates at Moorgate might let you
in because that does act as London Terminals. I don't know what is set
up for Paddington given the advent of FGW's gates plus the complications
of both magnetic and Oyster OSIs being present.
