Now you come up with the "if" situations ...
So "if" the speed decays below Valphamax it would mean you're over alpha max and that's the elevator job to correct back to alpha max and its corresponding Valphamax, not the thrust job.
If you don't like if, change it to when.
As for the rest, you are distorting my words to suit your own purposes. I made no mention of Valphamax, those are your words. I made no mention of flight at more than alphamax, in fact I said that you could not achieve alphamax, so in my world the situation you describe could not happen. I could perhaps have been more specific, and stated that the restriction to alpha can occur at any AOA between alphaprot and alphamax. You choose to interpret it as being at and only at alphamax.
I made no mention of speed falling below Valphamax, I simply spoke of speed falling - again at any AOA between alphaprot and alphamax.
