It works the way it works because of the "template" parameter defined in the Chapter navi (and it's no coincidence that that parameter is identical to the template's name). Without it, the links in the navboxes would point towards the articles the navbox was added into.

In other words, PAGENAME is used here as the default value for the "template" parameter to make the links on the base template page point to itself.
