Out on a home run?

[mastdk96]

Any other help on this one. I have asked a few other local umpires and say no one is out unless there is an appeal. Can R1 come back and touch home and everything be o.k.? Am I understanding right that a over the fence home run a dead ball, and no outs can be recorded unless an appeal? Wouldnt this be like any other base on a live ball and multiple runners that if they miss a base? "NO call until an appeal"
