I doubt the portal summoned him, but I would bet being a major--if not the biggest--reason Bill is there, but I'm also guessing there's more to it. What exactly, I don't know. Matteso makes an interesting point about Dipper's surprise to see Bill. Like I said before, if Bill came on his own will, he's definitely got some sort of complex plan for that episode, which is probably just a step in a bigger, even more complex plan. Tricky demon!
