The opening is indeed a little odd, and Pelosi is closer but couldn't have used his left hand because it has a drink in it, and his right is tied up by Depape. However it could have easily been opened by Depape using his right hand and he pulled back after turning the knob and pulling the door open.
Occam's Razor says there wasn't a third person there.
Who the heck opened the door?!

Which begs the question. Why would the attacker open the door for the police? This entire thing is super strange.
That's a fair question!
