As you know, how big a deal it is to get authorship in the search results. In fact, there are many who are missing their pics on search results. It seems to be clear now, that Google was in the process of testing its company logo of Google+ in the search results.
The pages won’t have the code rel publisher on it. The pages would, however have Google+ page that would have been verified and also a web site which will be linked to the Google+ profile.
So it is perhaps a feature that Google had been testing.
