My guess, with about 30% confidence is, CCM asked McD to wear something resembling their upcoming flagship skate at the ASG because that's an identifiable event. They can use that to say, "Look at McD wearing our AS-Vs in 2022!" without having to mention that he went right back to his trusty 2015 JetSpeeds. It's a little conflicting with that hypothesis that he wore his AS-Vish boots for a few games before the ASG as well, but maybe he really is close to being happy with them. Fedorov was in and out of Nike the first year they supplied him, so transitions from a skate the best skaters in the world know they love looks like it can be really tricky.
