It certainly needs a rethink, though I suspect this functionality was specified by a multi disciplinary team which included test-pilots. Not saying that it cannot be improved on of course. And there is no evidence to suggest it is the a primary cause of the accident.
Even if only a contributary factor. In a rational world, one would
expect the warning to be on at any value under the limit and stay on
until that value was again exceeded. I don't fly these machines, but
would find the present logic, off, on for a narrow window, then off
again, confusing and critically so in an emergency.
