I think he opened the door, so no restrained arms. IMO.
Also, the video seems to get particularly blurry when he is getting in the truck. The best I can tell, she didn't help him in. I think when she kneeled down, she was picking up whatever fell out when he opened the door. Then she moves to the driver's door, and you can still see his feet on the ground. Then he climbs in.
I do find it odd that he didn't pick up whatever fell out of the door, but more so, that he just stood there for a while before getting in. MOO
