You wouldn't have to leap off the train - the intermediate validation
would only need to be done at a station where you were changing trains
anyway.

Essentially, I'm guessing (from the list of stations provided) that,
for example, the Z23456 time limit will be enough to travel Z6 - Z2,
but not (necessarily, perhaps in the event of delays) enough to travel
Z6 - Z2 - Z6. So at the interchange station in Z2 (where you "turn
back" and start heading outwards again), there would be a validator to
touch which would extend your time.

My mind was leaping to an imaginary situation where in future you
might need to do this on a straight through journey from, say, 6 to
6. But I am still confused as to whether the time limits will be
applied to the assumed pair of start and end points or to a different
measure from the way that fares are assigned.

If the end points works for fares, then why couldn't every point to
point journey for which a fare is defined also have a time limit
defined, such that Heathrow to Wimbledon Park wouldn't need to have
just a standard 2 - 6 timeout?

Speculation overload.
