FWIW the conditions of use for Oyster
http://www.tfl.gov.uk%2Fassets%2Fdow...uL_YIr_fB1vJpg
do make the distinction between what you "should" and "must" do:

"3.16 Oyster route validators (pink card reader)
Oyster route validators can be identified by a pink card reader:

These are located at a number of interchange stations. If you pass an
Oyster route validator when changing from one train to another, and you
are using your Oyster card to pay as you go for any part of your
journey, you should touch your card on the pink card reader to ensure
you pay the cheapest appropriate Oyster single fare for the route you
are taking.

You must still touch in on a yellow card reader at the start of your
journey and touch out at the end to ensure you pay the correct Oyster
single fare."


(I was sad enough to check when they were introduced at Highbury &
Islington.)

The sign at Wimbledon also seems to suggest that you must touch the
pink validator if changing between tube and train, but as far as I can
see almost no one ever does. The confusion isn't helped by the fact
that there's yellow validators on the tube platforms, pink validators
just beyond the platforms, yellow ones on the ticket gates at the top,
and special tram ones on that platform - I think people have learnt to
ignore them unless they have to open a gate.

Well this *is* the same organisation which tells travellers that "dogs
must be carried" before they may use an escalator

I don't have a dog to carry! does that mean I have to walk up the
stairs instead?

The situation has been improved by the acceptance of PAYG on NR.

Previously, at Stratford you could ignore the pads at the end of the
DLR and on the Central platforms and touch out at the barrier.

But at Greenwich, if you didn't spot the validator halfway back down
the DLR platform and headed for the exit, you'd find yourself not
passing a barrier or validator. Now there is one at the main exit and
also the DLR one is a bit better placed.

PAYG on NR has only reduced the numbers of people needing the platform
validators, it hasn't allowed the facility to be removed - they are
basically there for people transferring to/from NR services that extend
beyond zone 6, just like those at Wimbledon.

What happens now if one touches on the platform pads when interchanging?
Does it terminate the PAYG journey completely or does touching out further
down the line make it an unnecessary interchange touch?

Many have been switched off, like at London Bridge. But I was getting
at the fact that there now always has to be something at the NR exit,
whereas in the past you might have missed the platform validator (as
on the DLR at Greenwich) and then not had the opportunity to pass
another one.

Apparently the system sets a sort of 'partial exit' if you are already
touched in; another poster here, 'Mizter T', coined the term 'soft exit'.
If you aren't already touched in it starts a new journey.

Whatever it is called behind the scenes, the journey can continue. I think
it gets sorted out either at a subsequent proper exit through a gateline, or
after some sort of timeout, whichever comes first.
