A different take

Hypothetically, what would happen if a player (already scored) pushes a player back toward home plate, then realizes his mistake and tackles him, thus preventing him from retouching? Would that then necessitate an appeal for a missed base from the defense since the offensive player didnt actually assist the player?

I'm pretty sure that's a 10-yard penalty from the spot of the foul, and loss of down.

J/R states that "a player who had been a runner but has touched home and is signaling to a following runner" is considered "another teammate." However, in the two situations given (Section VI), this scenario isn't listed, simply because no "play" was being made on the runner.
