That is a complete falsehood. Half the reason for the somewhat arcane annunciation logic employed in modern airliners is for the precise reason that cognitive overload is so feared and to be avoided. This is why Stall Warning quite literally trumps a whole host of others.
@Lyman - give it up. The aircraft did *not* climb due to autoflight input and autoflight did not move the THS. It was pilot input, pure and simple. The reason for the delay in disconnect and the message is purely because it takes some seconds for an initial ADR discrepancy to become a confirmed ADR DISAGREE status, as was mentioned quite clarly in the earlier threads.
