It appears that the “shooter” pulls the gun to his left before pulling the trigger. I think he might have been scared he was lied to and the rounds were real. So he aimed to his left just in case.
You’re probably right.
He screwed up. It’s right there on the video. He shot nobody. That’s why the Capitol Police officer on the other side of the door reacted with not one ounce of concern or panic initially, then, when he realized that he needed to at least make some kind of show of it, he pulled a kind of “Charlie’s Angels” turn to the side with a rifle point” (politely asking another one of the crisis actors to move to one side).
