Why does he do what he does? Well like The Doctor, he's become a guardian for the people of Earth. Like The Doctor stayed for Christmas, so does this Timelord! 
But more seriously, it'd be a more upbeat way of continuing the Gallifrey plotline without actually having to take it very far at all... some Timelords have managed to get back into this Universe, not all of them good, but also not all of them bad. The Doctor is not alone though, and that'd be the message. Schmaltzy Christmas stuff, but it's going to be no matter what, so why not make it count?
