Well, however they do it, I'm not sure why you seem to imply it's a bad thing.
I was only responding to a comment that if there's no Z inventory, they might not upgrade people even if there are seats. From my read on the new policy, that won't be the case.
Whether they rebook you in Z or just reassign your seat - doesn't really matter to me, as long as they allow day-of-departure BE upgrades.
