They unflex because the load is removed. In order to stall they would
have to unflex faster than the load is removed. If the pilot is pushing,
the stall speed can go _way_ down. It's when he starts to load the wings
again that his technique, or failure to track his loss of airspeed in
the pull/push, can bring about the stall.

Isn't it also true that lift will be reduced if a highly flexed wing
increases its angle attack beyond the critical angle of attack. If
the wing is producing less lift it cannot maintain the flex that
existed before the critical angle of attack was exceeded. As the wing
unflexes the tip angle of attack increases.

Which of those assumptions is invalid?
