I agree that it's a slightly odd way of describing the situation, but it is true that this is a _different_ kind of architecture update than what Intel has done for the past few years, which is worth pointing out to readers. For people who are not up to date on Intel's roadmap, this update is distinct from what has happened before, and therefore anomalous.
