I think Obito needed to teleport to Kamui Dimension before teleporting to a new location in the real dimension. I still think it was pretty fast though, especially considering it had no limits in terms of distance. But I wonder if he needs to move in Kamui's dimension to teleport to a new location in the real dimension.
