I agree, but, playing devil's advocate, if a later episode were to reveal that he is a previous incarnation, nothing in this story would explicitly contradict that. I highly doubt that will happen, though; O having his temper tantrum on Gallifrey, then regenerating and nudging 12 to rediscover the Gallifrey they'd already destroyed in the future would be odd.
