I'm not exactly sure.

My normal experience of Tube trains going through temporarily closed
stations is that they may slow to 5-10 miles, but they don't stop. I guess
that they are similar to draw up signals in that they will clear if
approached at a certain speed, assuming that there is no train ahead of the
one in the station.

I suspect the approach control signals are still there so they have to
slow for them.
