You wouldn't have 2 certs for that... I'd have *one* cert for that. And if when
you got to the IP address you were trying to reach, the cert didn't validate as
matching the hostname, you know something fishy is up.

And if you *do* have two certs for it, I'd like to talk to the bozos at
Thawte and Comodo who obviously didn't check the paperwork. ;)
