When you link your Google Profile to your author pages (or to sites you write for), you're telling Google that all of these pages represent you. If your content appears in search results, your photo (including a link to your Google Profile) can appear next to it. Content you’ve identified as yours will also be listed on the +1 tab of your Google Profile.

Looks like someone rushed that page out the door. The headline says "Link your google profile to your site..." but your actually linking to your profile FROM your site.
