Does the run count?

Runner from 1st thinks he is out and starts walking to the 1st base dugout. By "retreating" does this reinstate the force out? If it does, then the run would not count.

If the runner from 1st "R2" stopped before he reached 2nd when he saw the throw heading towards F4 from F6 and turned back towards his dugout thinking he was going to be out and F4 picked up the ball after dropping it and touched 2nd before R2 turned and got to 2nd then you still have a force out at 2nd. no run would score as the 3rd out was via a force.
By "retreating" towards 1st he is not removing or reinstating anything, the force at 2nd still exist.
