Does sandbar really live in ponyville?

In the episode Hearths Warming Eve club, everyone pony leaves The School of Friendship, except sandbar, then rainbow dash says, "Yeah, shouldn't you guys be leaving, if you miss that train it's a really long walk." And later in the episode, it's stated that sandbar lives in ponyville, but he stayed with everyone that lives outside of equestria, so do you guys think sandbar really lives in ponyville?

He does seem too, at least while attending the School. He stuck around in Uprooted, too. On the other hand, he is seen leaving on a train in Best Gift Ever, but that might be to spend the holidays with one of his friends or relatives.

So the next question is, how long has he lived there? Was he in the background unnoticed all along, or is he a recent transplant? I prefer the latter (especially since his name and cutie mark suggest a coastal origin) but the former could make an interesting story.

I would like him to have been a background pony, I'm not sure why. It just seems better them him recently moving there.

I have a feeling that he just moved to Pponyville recently for the school. It just feels so.
