I view it differently than both of you. I don't know the physics AND I don't think physics is the key issue in the scene. Yes the scene bothered me as I think the timing/editing screwed up this scene. The guy seemed to let go at a point it became completely unclear that he HAD to. Now, I, the viewer 'leaves the film' thinking that what happened didn't connect to what I saw. They just overplayed their hand or in short, they went several seconds too long before he disconnected. Terrific film in my view but I thought they mucked that moment up, big time.
