Right... :P

Anyway, the only fact we have at present is the Doctor's word — they are the same woman. And, so far, there is no evidence to the contrary. It would be speculation to assume that he's wrong. Until we have hard evidence that they're different people, he have to go by all we have:

"I never knew her name, her full name. Soufflé girl. Oswin. It was her. It was soufflé girl. Again. I never saw her face the first time, with the Daleks. But her voice. It was the same voice. The same woman, twice. And she died. Both times. The same woman!"
