No, couldn't be, as Minato and the other users have proven to teleport other objects with it, without moving themselves. It is not about perception, as the manipulation of perception could not teleport a tailed beast ball, and a technique that could alter perception on a scale large enough to make it seem as though Mei had teleported to the battlefield would be far to difficult for Minato's bodyguards to perform, even as a group of three. If it was activated by speed, then Minato wouldn't have been able to teleport the tailed beast balls. It is simply using a dimensional intermediary to get from one place to the other. That's it.

Also, it was Tobirama who first made the technique, so Minato couldn't have created it as some sort of extension of Shunshin or something like that. The two techniques are different, and that's all I was trying to explain.
