Is he okay? My friend took this video i was in the restroom when this was going on (check description pls)

I have NEVER seen my girlfriend’s rabbit, or my rabbit do this before so I’m very confused as to what’s going on. A sign of splay paw maybe? Because he is on a hardwood floor 1/3 of the time he’s running around. I’m very worried. My buddy tells me he was “flopping around” prior to this, and he had just pooped on the floor as u can see lol. He is not neutered and he is either 5 or 6 months old.
