I don't see any similarity between the plays.
That's because they aren't similar. In one instance, a guy is on top of a goaltender and is making no effort to move away from him. In the other, a player happens to slightly touch a goalie driving to the net.
An argument can certainly be made that Anisimov "restricted the goaltender's ability to move freely within his crease or defend his goal" more than McDavid did considering that in the incident in question the goaltender was able to get back in position after being contacted whereas Andersen had to deal with having Anisimov draped all over him while a goal was being scored.
