Morning, sorry to say but you’re incorrect.
if you still have access to the stall charts, have a look at the compressibility effect on stall speed above 25000’ on the 320/321. Plenty of occasions where V alpha port will exceed Vls and green dot in a turn.
the AP will disconnect, and you will be hand flying at max Alpha. If you’re close to the Rec max, you’re only option will be to descend to regain energy.
or.....
you can go Green Dot + 10.
