Honestly I haven't seen him move, but either it was bad timing or the movement was removed.
@sadbunny said he saw him slightly move, but we never saw him move during his initial run so not sure how it compares.
Either way, I'm glad that room isn't triggering scares with nothing in it anymore.
EDIT: Looking at this footage, I'm pretty confident the movement has either been significantly toned down or just flat out removed, almost sure he doesn't move this much anymore.
