No, it's a backwards jumpkick, like it says there. Press back, up and 3 at the same time in order to perform it (you can't delay the kick). Use 3 instead of 4 for the jumpkick, because otherwise you'll get a divekick instead of the kick and then the teleport. Maybe what you're missing is the teleport; the timing is a little bit strict, so what I do is tap 3 and meanwhile press down, up really fast, so that the jumpkick, the teleport, and the 3 after the teleport come practically all in one.
