The best thing I can come up with is that he didn't want more gatherers to be able to come up from the prisons so he sabotaged the elevator then hid the machine room key so no one could fix it while he did his whole 'self-inflicted-amnesia' bit?

Pretty weak ideas but it's all I got. I'd like to see what others might have come up with!
