In fact, the Contact URI and the From URI are generally different anyway, since one is an AoR and the other usually isn't. This is fine, but is not an example of third-party registration. > From: The From header field contains the address-of-record of the > person responsible for the registration.

This extract actually says that the From header needn't be the same as the To header, for a third-party registration. It doesn't mention the Contact header at all.
