If he worked on it and could convincingly fake it, I - as a recruiter - wouldn't care too much if he embellishes a bit and claims he also did it from the start. Maybe he factually didn't, but if he's good enough to make me think he did, there's a decent chance he would be good enough to actually do it for me. Not a certainty, there's never certainty, but a good chance. Of course, given the choice, I'd prefer the one who actually created it, but one who worked on it and knows it well enough is not bad either.
