As stated, I think this rule is more administrative in nature, meaning that if any penalty is going to come, it will come from a league or conference to enforce some sanction. Otherwise right now there does not seem to be a subscribed penalty to give if we notice two players are at the same position.

The subscribed penalty is on FR-21 of the 2013-2014 Football rulesbook

e. Two players playing the same position may not wear the same number during
the game.
PENALTY [d-e]—Live-ball foul, unsportsmanlike conduct. 15 yards from
the previous spot [S27]. Flagrant offenders shall be disqualified
[S47].
