I have heard two instructors in the past 24 hrs try to sell me that rubbish during development training.
The accompanying patter actually amounted to a recipe for disaster...
The instructor schools responsible for their initial training should hang their heads in shame...
Simply put, rudder controls yaw. Prevent yaw during stall entry (assuming non-turning stall) and recovery using rudder (best achieved by having Bloggs focus on a reference point throughout entry and recovery and work his/her feet to keep the nose "locked on" in the yawning sense). Who cares about the wing "drop" if there's no yaw? Any wing drop can be corrected with aileron once the wings are unstalled (ie elevator control forward of stalled stick position).
Easy, and guaranteed to avoid a spin (which is part of the point of this).
Spin avoidance for dummies (like me!) - prevent stall and/or prevent yaw. Done!
Stalled stock position - not taught in schools these days and not understood by the vast majority of pilots... but don't get me started on that!
Happy stalling!
