Intelligent linking throughout a website has the effect of distributing, circulating, voting the PR that normally accumulates on the home page to the internal pages. But any links from anywhere on the web will help to spread PR.
The natural impulse to keep click paths to all pages short also tends to optimize PR distribution.
His example is the classic case of the shopping site, where the usual mindless hierarchical structure leaves the all-important product page hanging out there with perhaps a single internal link pointing to it.
Hopefully, people will continue to overlook this point. It's one of the best competitive tools a white hat content developer has at the moment, IMO.
Fortunately, it seems like the vast majority of webmasters just cannot grasp that googlebot sees your website as a directed graph, as specified by your internal links, and doesn't care a bit about your "directory structure". I predict most of them will continue to force content into a simple hierarchy and fail to use link density to provide ranking boosts that internal pages often need. And the myth that you should put everything in the "root" directory will probably still be alive and well 10 years from now :-).
The last time I did this both new pages got a PR 6 within a few weeks of being online and my home page is only PR 5.
Note that this particular phenomenon is neatly explained by the theory that says green-bar PR is uptodate for new pages, but not for older pages (which is to say, when things are updated, your home page PR will suddenly be revealed to not be lower than your "new" pages after all).
