Sure, but it’s not via anything mystical. If your main page links to your inner pages, you are sending the inner pages PR. If your inner pages then linked out to disney.com or something that didn’t send you back PR, then you would not be lower your index page PR, but you would be missing the opportunity to raise its PR.
Simple example… you have a PR5 main page. You link to your own page2.php, which becomes PR4. page2.php links to disney.com. You still have a PR5 main page, but you would have a slightly higher PR5 if your main page was being linked to by page2.php.
This follows through on all your pages. The more PR you recycle back to your main page, the stronger your main page is. The more PR you spin off from your subpages, the less pop you have left to send back to yourself.
