I don't think it a version of the Doctor that is the first or before because as palitoy states Clara saw all of his past faces. It could be that if he is the McGann Doctor once he chose to end the Time War with the Daleks the way he did ( wiping out the Time Lords and the Daleks ) he to do it as someone not the Doctor and Clara only his past as the Doctor. I think he is still technically the President and maybe he ended the Time War as the "President".
Here is what is said in the show.
(Matt Smith ) I said he was me, I never siad he was the Doctor. The name I chose was the Doctor, the name you choose is like a promise you make. He's the one who broke the promise.
(Hurt) What I did I did without choice
(Matt) I know
(Hurt continuing) in the name of peace and sanity.
(Matt) But not in the name of the Doctor.
