Discharging a cap from 3v3 using a PNP

It's a strange situation because current flows into the 3v3 line.
Since the surges is in the order of 200mA, maybe this can lead to
problems?

EDIT: no of course not.  No current flows into the 3v3 line.  Current
flows out of the cap down through the PNP and back into the cap --
exactly the same as in the NPN case.  My intuition about the NPN case
was wrong though: no current is flowing into the ground either!
