I flipped back a few comment pages and read that someone said that this wasn't "Efficient Forward Motion".
Doing a triple back-handspring could be efficient forward motion if the situation called for a triple back-handspring to be done. Who is anyone to say that what he is doing in that picture wasn't the fastest way over? Maybe there was a car speeding at him out of the shot, and instead of going the other route around, he chose this route.
No one can assume that much, even. Don't assume it wasn't efficient; only the Traceur himself and the photographer are apparent witnesses of this.
As a Traceur, myself, this is a nice shot. His leg is a bit high up - I wonder how he landed it. Such a powerful jump, too.
