Indeed, "possibly" as in "not demonstrated, and will not be either way".

the "gaining of speed" is still important. It is part of the solution/recovery, and the change of AOA - bring the nose down - is a means to achieve just that.
Uho... Perhaps is the procedure not perfectly written. On the other hand, I disagree when you write "the change of AoA is a means to achieve a gain of speed" (if I understood correctly?)
It's the other way : the gain of speed is a mean to lower AoA (all other parameters equals). And lowering the AoA is what is important to avoid/exit a stall.
