Don't forget that traditional as well as modern martial arts are taught for self-defense and character build as well as the history. This is not a real fight situation its more of a contest which means nothing in real self-defense. A real kung fu master probably would not have any reason to fight that guy taking what ever shame it will give him. Also, that guy looks to be about 3 times that guys size and just laid on him and over powered him which is nothing impressive and he broke the guys arm which means he is nothing but aggressive powerhouse with no control.
Like we all said before it comes down to training not the style. To many people get sucked into the fact that they are the best at their school and will not leave to test their skills else where trying to implement and further their knowledge.
