Don't know what else you could call it. BR is running to orange bag, following his allowed path, and has no obligation to do anything other than not interfere on the white bag. Once F3 beats BR to the base, BR is a retired runner, and you have to have intent to have interference on a retired runner.

I can't see penalizing the offense because F3 can't run to the base without crossing into the BR's expected (and required) path). Only way I see a call is if F3 and BR make contact before the base; in that case, we have a collision with a defensive player with the ball and a BR; BR must slide or otherwise be accountable to avoid interference.
