I don't think Google would agree that it's okay to ascribe articles written by different people to a single author.
Well, Google doesn't seem to care so much when a "single author" ascribes to himself other people's content without consent (aka plagiarism, scraping). So does it really matter when a group of authors work under one pen name. It is even reasonable to make it possible to build "authority" rating for a group like that.
I am quite sure that Google wouldn't like that, but what I am trying to say I guess is that ethically it is not a big deal.
