From the EAD (emphasis mine):
An A330 aeroplane experienced a blockage of all Angle Of Attack (AOA) probes during climb leading to Autopilot (AP) disconnection and activation of the alpha protection (Alpha Prot) when Mach number increased.
If in climb phase, would we not be talking about a significantly different scenario than cruise, given that it would be starting from a higher positive pitch and thrust setting?
