Dominion sometimes spreads in a funny fashion that way. Not necessarily always wrap-around style, I've had dominion candles pop up in random places across the map and then spreading out from the original point of contact. It's been going on since DomPPP. Sometimes that can happen as the result of events (e.g. AI gets the "People have been led astray by a false god" event and the computer randomly draws you as that false god).
