CR was talking about what the HP sound stage sounds like.
All this test is saying is that the HP calculates and puts out the same sound stage in different rooms.
CR's test (from what you could see in the short video) appeared to be limited to sitting directly in front of the speakers. Wired is saying that the HomePod doesn't require the listener to be in a specific spot to hear the best reproduction. CR never addressed that aspect of the HomePod in their initial rating.
