Guy with gun moved to where the runner was going.

Guy holding gun moved forward, but he did not cross all the way to the other side of the truck to intercept Jogging man.

Jogging man closed that distance.

But you are correct that Gun guy stepped over the yellow line.

“Guy holding gun moved forward, but he did not cross all the way to the other side of the truck to intercept Jogging man.”

He was not seen from 15 to 20.

At 20 he was moving backwards in front of truck.
