I read the help, it's another Google attempt to force people to use their social networking features, Google Profiles in this case. Much like Panda, it sounds like a beauty contest, starting with the instruction that you need to add a good "head shot" to your Google Profile.
Next you have to get a code snippet from Proflies to add to any web page you want linked, and then you have to link back from Profiles to the page. Wasn't clear if the link back is required for every page or one per site.
Other than causing your Profiles page to appear in Google before your website, blog, or whatever, it's not clear whether this is useful. If they would announce "the pages you claim as author will be used as a signal to stamp on copyright infringements" I'd do it.
