Never said they weren't choreographed. It just looked like people actually fighting, vs people dancing around. Darth Maul flipping around everywhere looked really cool. It did not look like he was trying in any way to kill or even hurt Obi Wan or Qui-Gon. It looked like he was flipping around for the sake of being able to flip around.
Spoiler: Totally fighting, and not just trying to look cool
