That's what I figured. But then I'm trying to think of any examples where I've seen both www and non-www pages from the same site returned in the SERPs - ie, examples.com/pages.html and www.example.com/other-page.html. I don't think that happens, but I haven't really paid attention to that much, tbh.
It's a case like that were I wonder about verifying authorship on both versions of a page, particularly if pages are verified on a page-per-page basis (as opposed to one Authorship connection in a universal footer) or multiple authors on a single domain.
