The tanker version appears to target a different issue.
On the MAX it was specifically to counter a situation where the stick was being pulled back well past the cutoff switch activation point.
I also question the statement about repeated cycles. We know on the MAX a manual electric trim input resets the system. If not for the MET input it wouldn't move the stabilizer again until AoA decreased, and then it would take out the stab trim it added.
What resets the system on the tanker?
