Is Director Vance actually another person?

In the 6^th season of NCIS, we come across an episode (Knockout), where Tyler Owens, a boxer and a friend of Director Vance, is found dead. Vance starts leading the investigation, and Gibbs become more and more suspicious as he finds out:

that the deceased, a supposed former Marine, doesn't have a military record, yet Vance says he was a Marine;
that Vance told his wife he was discharged from the USMC because of a detached retina, and the deceased had a detached retina.

We then find out that Vance was involved in a black op (Operation Frankestein), which he basically invented just after getting out of the Naval War College.

Gibbs has a file on Vance from the CIA, but never opens it. However, he seems to hint at other characters that the Director may be another person.

The question is: is Vance actually Owens? If so, is the replacement Owens/Vance somehow related to Operation Frankestein and possibly other black ops?
