I don't believe that's the case here. This specific instance speaks nothing of how "connected" everyone is, it shows that if you are notable (enough to warrant a mention somewhere online -- as this guy was and that's how he was found) then you can be located easily. If this guy had been anonymous and unknown I doubt we'd have seen the same result. This also has nothing to do with google+ beyond it being the platform for discussion used, the post could easily replace "google+" with any online discussion platform, hackernews for example.
