I dont see how mirror flop can effect drift aligning. You are aligning the mount and not the scope. Once you have chosen the drift star you just keep going until it stops drifting. Usually you slew at two or four by to recenter the star in the eyepiece after adjusting the mount knobs. In drift aligning, mirror flop would at most be equivalent to cone error which doesnt affect drift aligning at all.

The problem with mirror flop is that it affects focus.
