I don't really pay attention to credit card world but my understanding from conversations with friends on both sides is that the promo code is just unique to the UA employee (flight attendant, club agent, etc.) that gets credited for the sign-up and not to a specific sign-up. E.g. the same promo code can potentially be used thousands of times for a particularly prolific flight attendant.
