Ah. So a remote access may be coming directly from the cache of a different CPU? That's something I didn't consider, and definitely adds another wrinkle.

I sense that the article is saying things in confusing ways, perhaps because that's the way computer architects speak (it always struck me as counterintuitive and confusing to measure a cache by its miss rate rather than its hit rate) or maybe it's this article.
