Ever heard of this weird NHL overtime rule?

are there any weird rules that people don't know about the NHL or hockey funny enough one that came to light earlier in the 23 24 season was that if you're in a three on- three overtime period and you pull your goalie and even strength and you get scored on with an empty net you actually don't get the point that you would normally get for losing in overtime if you get scored on the other team gets two points you get nothing so if you play at even strength and you get scored on in overtime you still get one point but if you pull your goalie try to get an extra advantage and you get scored on you don't get anything
