Wing drop recovery
When a wing does drop, its downward movement increases the AOA even more, thus bringing it deeper into the stall. Using ailerons at that moment would not be of any help at all as picking up the wing (downward aileron) also increases AOA but then at the wingtip. The stall is now developed from wingroot to the tip.

The stall/spin accident is aviation’s #2 killer of general aviation pilots. This is in part because during training the modern airplane has to be forced to spin and it requires considerable judgment and technique to get the spin started when loaded with the student and his instructor. However, when a passenger or baggage is added to the back, this same airplane may be put into an accidental spin with surprising ease.
Spin avoidance is a matter of practicing cross-control stalls until a conditioned reflex of using the rudder is ingrained. During a power-on stall where the wing falls to the left or right, the pilot who has not developed the conditioned reflex of using the rudder will instinctively apply aileron to stop the roll. Modern airplanes, those built since the late 1940’s, are required to have aileron control during a stall. This control is not sufficient to stop the roll without the addition of rudder. In fact, when the airplane rolls to the left and right aileron is used to counter it, the left aileron is deflected downward to increase lift on the left wing. Lift and drag are directly proportional, so the increased drag resulting from the increased lift may actually aggravate the problem.
If, instead of aileron, the rudder is used to “pick up” the wing, the airplane will not spin. To set up the autorotation required to develop a spin the nose of the airplane must turn or yaw at least 90 degrees. Rudder will stop the turn and prevent the spin.
I have trained more than 2,000 primary students and each one performed a spin prior to their first solo.
And somebody we may know?
Using The Rudder - Aviation Safety Article
Compare what Mr. Laming says aka "
At the low speed normally associated with a stall, the so-called “pick-up-the-wing-with-rudder” technique he advocates has the potential to cause a spin in the other direction" to the bolded piece above.
