Of course not. All air data sensors are influenced by a combination of airspeed and angle-of-attack, in addition to environemental factors which are not exactly the same at sea level or 41,000 ft.
During this stall sequence, what in fact outvoted the alpha probe was the very high alpha achieved ! Alphas outvoted themselves by making other probes displaying wrong values.
Certainly that this was never considered remotedly possible. But keep in mind that limits still apply for everything flying.
Say, maybe this aircraft is able to fly at Mach 1.2 without falling appart. Would you ask for its probes to be certified for not stopping an overspeed warning at such a speed, in the very remote case that someone would ever try it?
