Very curious sport though, how violence and punch-up are so common and encouraged, often (as in that clip) with the referees just standing by and watching.

…refs let them punch themselves out unless they fall on the floor then they will step in.

Here is a pretty good summation:
“Fighting is considered to be part of the game in hockey. The unwritten rules actually provide pretty strict control over what looks to be uncontrolled. The refs always step in and end the fight when one of the players falls to the ice. At that point, the fight is over. If one of the players continues to fight, he will likely be ejected from the game.”
