7.09 it is interference by a batter or a runner when-
(i)In the judgment of the umpire, the base coach at third base, or first base, by touching or holding the runner, physically assists him in returning to or leaving third base or first base.

Neither, that's judgement.

Are you watching the same video...the assistant coache shoves him off the effing bag in the direction of second and the runner takes a couple of steps before changing his mind.

Was the runner trying to advance? No, judgement. Absent an "assist" (just touching the runner doesn't constitute an assist) I've got obstruction and he's going to 2nd. That's judgement.

Judging from the video...poor judgment. At the time of the assist the runner did indeed take steps towards second. Changing his mind and coming back does not negate his initial action.
