Ok I asked for an example and you provided one, that's fair. It also makes the second domain a target. I had someone issue a cert on one of my subdomains because I forgot to remove DNS after cancelling a VPS, and the VPS provider didn't remove the reverse DNS so they found it. Small attack, but it happened.
