It’s off topic, but I don’t think that’s the reason for the nose up pitch trim at 400RA.
I think the reason is to allow the aircraft to pitch up gently rather than crashing onto the runway in the event of a autoland flare failure (given that it is only dual autopilot) if there is no pilot input after autopilot dropout during the flare.
And it’s not a massive trim input, it’s a small trim input easily handled by a pilot.
