And according to the past comments over the years, "Continuing action" stops when it is clear that one or more players have stopped after the officials have killed the play. IMHO that applies here and does not change the clear and obvious, albeit using UHD replays, that the ball was touched.
I'm not a Replay expert. But I think we've already been given an answer in this thread by one or two people who are Replay experts. And if we're wise, we'll listen to them.
In my view, Replay continues to evolve and be refined. After the Auburn - Arkansas game (attempted spike play), they gave more guidance regarding "the immediate continuing football action". To make it even clearer. They primarily directed that to the Replay Officials and the Coordinators. But they also talked about it on the national training tape.
They stressed that it's "the immediate continuing football action". If players in the vicinity of the ball continue to play it, regardless of what other players on the field do, then that's immediate continuing football action. It is a judgement call and they expect Replay to use good football sense.
I agree with what the Replay experts have already told us about this kick play. That's a touch of a kick and that's immediate continuing action.
