You are right moreflaps that exercise is the imfamous keep it in the stall tap dancing on the rudder pedals which the CAA in the uk has been trying to stamp out for some years now.
The only thing that should be taught in the stall or very near near it is to reduce the angle of attack and then return to safe flight. All this faffing around with exercises just instills the idea that there are other things to do and it is normal to be back at this very dirty side of the drag curve.
