SDO?
SDO is normally used to allow one set of doors to be off the platform,

No. On National Rail it's normally used to allow one or more carriages
to be off the end of the platform. eg at Billingshurst, where it's
common for 8 carriage trains to stop at a 4 carriage platform, or
Battersea Park where 8 carriage trains stop at a 7 carriage platform.

not an entire coach at each end.

You're right about that though. Trains normally stop so that the front
or the rear of the train is at the platform.
