Yes, I saw the same thing last week and thought it was silly but after looking more closely the unit was right up at the signal.
It means the passengers have a bit of a walk I suppose but if needs be would allow another unit to enter the platform behind it.
Many station platforms have stop boards so trains do not run to the end of the platform where it is convenient for passengers to stop short. I wondered if there was a rule which prevented that in this case or whether it was just that no one thought to do it. It looks as if it is being treated as a terminating platform where trains run right to the buffers, even though it is also a through platform.
