That's what I thought too but then I noticed that someone bothered to put "- Nick Janetakis" in the titles of those PDF pages (check the screenshot in the article).
I don't think that's exactly what was going on though, although perhaps somebody else can chime in.
I don't think the "- Nick Janetakis" is actually in the title of the PDF, rather google has appended it to the actual title (the end of which has been replaced with an ellipsis).
I think google can get this from either the title of a html page or from a og:site_name entry of a html page (I'm not 100% on all this). It's possible that google took these from the "actual" ssl.nickjanetakis.com and still remembers the og:site_name and applies it to the pdf files?
I think that may be something Google appends to its search results for some links?
I googled my own domain (site:flurdy.com) and it appends "- flurdy" to some of my static pages. But not for all, especially not for subdomain apps. So I am not 100% sure.
