11th off then back on

Doesn't that leave you open to:

Sub enters the field and the huddle breaks immediately. Three receivers go to the opponent's side of the field, as one goes toward his own side of the field. Defender is lining up opposite him, jogging with him in expectation that this player will stop, and the player just continues right off the field, leaving the defender hopelessly out of position.

I realize from other posts that there's an NF rules against intentional deception, but what if it's not intentional - it still leaves the defender at an unfair disadvantage, so should be against the rules. Is there some other NF clause that disallows such actions if there's no intent to deceive?
