Stop teaching people to prevent wing drop with the rudder. Stop teaching people to pick up a wing with the rudder. This is what pilots may do when a wing drops for real and they spin in and die.
Whilst it's all very well to demonstrate it as a technical exercise it is bloody dangerous to have it in the memory bank as the correct reaction to a wing drop. It doesn't matter if the wing drops. Stick forward to recover from the stalled condition, roll the wings level when you have sufficient airspeed, and then recover as necessary.
I have had an FO stamp on the rudder in a Global Express on approach at about 200 feet because they thought the wing was stalled. Please stop teaching this crap now!
