R1 at 1st. Batter hits a triple, touches 1st and 2nd and stands on 3rd. R1 misses 2nd, touches 3rd, and slides into home on a play where the ball goes out-of-play. The defense is screaming that R1 missed 2nd and to appeal. R1 gets up and runs back to 3rd on his way to 2nd.

Questions:
Can R1 go back in reverse order to touch a missed base on a dead ball? And how does this affect the appeal?
Does the batter-runner need to back-track behind R1, i.e. go back to 1st, so that R1 can occupy 2nd?
