Isn't it possible
that the push forward makes the wings unflex at a rate that leaves the
tips stalled?


No.
The wings unflex as a response to reduced angle of attack and thus load. It
does not make sense that the wing could unflex faster than the load being
removed. If that was the case, then the wings would not flex in the first
place.
