starting game clock

[BEAREF]

NCAA rules:

I was watching our local DII college team play last night and there were a couple plays that I have a question on. Both plays were pretty much the same and were administered the same. I am confused on why the game clock was started when it was.

A running play around end and the ball carrier end up being tackled out of bounds. There is a holding penalty on the offense during the run. They administer the penalty and the game clock started on the ready for play whistle and not the snap. As I mentioned this happened twice.

I thought that it should have started on the snap. It would have at the high school level correct?
