The play's been getting a lot of discussion-time on the ref boards... most of the discussion regarding why it wasn't flagged. That kind of deception (making the defense think the snap isn't imminent) is illegal at both the NFHS and NCAA levels (the video is from Corpus Christie, TX - and Texas uses NCAA rules even at the high school levels). The team should have been charged with a dead-ball USC and the play whistled dead as soon as he took that snap and started "counting" steps. The only thing we can figure is that the middle school level in Texas uses different rules than the NCAA and the NFHS.
If anyone here in Virginia tries it, they'll get flagged just like they would if they tried the "wrong ball" or "where's the tee" ruses.
