Of course, now Jack is aware of his trick so it might not be so easy next time. But, he might find a way.

Although, will they actually get free? We saw a glimpse of their arms, they looked too inhuman in appearance to be used in Supernatural too often. (You know how almost all creatures have a human appearance or, in demons and angels' case, vessel)

Oh, and is this the second time in the series we see a character teleport onscreen? First being Chuck at the end of Season 5. Usually it cuts to someone else's face then shows the teleporter (usually Castiel or Crowley) gone. Or, suddenly there. Here it showed Asmodeus disappear.
