If he is an actor playing the part of Biden, there are numerous things that are done to help the actor stay in character......things that will make him walk like an old man etc. They do things to constrict the stride as the actor walks so he "can't get out of character" accidentally. THINK MOVIE

His walk was that of a frail man. Then, he just about bounced up from the fall.
Seems strange.
