2 is better than one
That's the thing. The NHL vaguely agreed to go in 2022 and 2026, but we all know that the ownership side does not want to go and only gave that agreement as part of the CBA negotiations. The covid situation gives the NHL an easy out for 2022 for a variety of reasons.
This is pure speculation but I'd guess that if the 2022 tournament were not in China (or USA/Canada) the NHL would already have pulled out citing uncertainty regarding covid and the Olympics.
I think you're right. There really isn't any benefit to the league/owners.
