Those two seem mutually contradictory. There's plenty of time to change
the points while each train is stopped in the station.

When I get some time I shall re-run something on a simulator that
shows why a platform stop right next switches either upstream or
downstream of a convergance point does reduce theoretical headway be
it conventional block or moving block signalling.
