Okay I was slightly off on the rule. It falls under Rule 9-9 Art. 1:

A player or nonplayer or person(s) not subject to the rules shall not hinder play by an unfair act which has no specific rule coverage.

Once this type of action "Wrong ball coach" or "I forgot the tee let me go get it" stuff like that takes place, the whistle should be blown when its evident that the offense is using action or verbiage designed to confuse the defense into believing there is a problem and a snap isn't imminent is beyond the scope of sportsmanship and is illegal.

Its really not that different than say the hidden ball trick. The penalty is unsportsmanlike conduct. 15 yards.
