Wow - well spotted! It definitely looks like he purposefully moved aside. To the non-aware it appears he was just moving but taken into the whole hoax context it does appear that when he says "this is not it" he moves aside to show the Sony label. That almost seems too deliberate in my opinion. Great job.
Personally, I always thought Jermaine was too happy during that interview and when he said "this is not it, there is so much more", what a strange and self-serving thing to say if your brother has really died. That was before I beLIEved in the hoax and at the time Jermaine's comments really confused and angered me. Now I think he's just playing his part really, really well.
