I didn't know the northbound platform had been extended over the
crossover. Does this mean a southbound train using the crossover to
enter the northbound platform has to go beyond the platform before it
can reverse and become a northbound train?

Ah, no, because like many Bakerloo stations, the platforms are on the
outside, unlike the island platform layout that was used on the CLR.

So from the platform, you simply look across the crossover. I should
have said "beyond" rather than "over".
