The last air bender northern wushu?

i saw the live action movie(it was awesome)and the scene where zuko is sparring on the ship against 5or 4 people is he using northern shaolin because i thought that style was long range and he was using a lot of joint locks and throws he doesn't really do this in the series(i have not watched the series in a while) i don't wanna hear that movie was bad cause i have my own opinion
