What's this about a backwards attack?

Sorry if I'm getting here late, but the search doesn't function doesn't work Anyways, at the part in Nar Shadaa where you have to defend Han, I was fighting about eight guys with a saber doing random attacks left and right. All of a sudden Kyle turned around half way and instead of swinging slowly and deliberatly like normal, he took the saber in one hand, looked back, and did a quick slash behind him, it took out two guys at once. So far it's the only move I've been impressed with, it looked like an old Japanese sword technique the way he kinda pulled his arm in at the end of the motion. I can't figure out how to do this move from a standing position and have only pulled it off while trying to do something else. I was using the default style (only one I have access to at this point), does anyone know how to do this consistently? Is it different than the "cheap" move everyone is talking about?

The back stab can only be done while an enemy is standing behind you. And it's not considered "cheap" in single-player because A.I. doesn't bitch.

There's some cooler moves though; like the matrix dodge and get-up.
