I'm afraid I'm not getting why this is significant: "Google traffic to odd pages that are one click away from an important page"

You're not.

This is how it has always worked from day 1. Basically any page "one click away" from an important page is linked from an important page, so of course benefits from a link from the important page. "Get links from important pages" is hardly news.

This isn't how it's always worked. This isn't about getting links from pages to a page, boosting the IBL-based scoring for the given page, this is about associative data modeling.

Robert, if you'll recall the previous discussions, for lack of what to call it, I referred to it as the "two hops back" phenomenon.
