No it didn't. That play was plain and simply not a slash. They even replayed it and it couldn't have been clearer. That wasn't even ticky tack, that was a phantom, and if you don't play for the puck when you are in front of the goalie, you don't deserve to play on a team competing for the gold medal. Canadian fans denying this just goes to show how credible they are on analyzing what happened.
The ref flat out chose to make a phantom call to deny the US a PP so as "not to get involved" and in process, she got more involved. That's why you do not make calls like that.
