It looked like the starter was touching or checking the window latch, then the crew guy tried to open the door and re-close it. Maybe the latch wasn’t working.
Starter quickly grabbed him and swung him back with enough force that he fell to the ground. (The competitor was pre staged during the commotion)
Both parties errored but the starter went over the line physically and could have seriously injured the older gentleman if he had hit his head while going down.
