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.

IIRC slowing down and/or briefly stopping at closed stations are the
result of near misses some years ago involving persons working at
temporarily closed stations being endangered by some trains passing
through at full speed and moving loose materials with the
consequential air movement. On lines without any approach control at
the particular station but where headways are usually short the trains
will often be stopping as usual at a red platform starter but without
the loading/unloading of passengers which usually coincides with the
time taken for the signal to clear.
