Exactly his point: A lot of the Google services hosted within a Google account essentially served as independent accounts themselves, each with their own independent sharing model/systems divorced from the others. Google's trying to switch over to a new system there's just one generalized Google identity (hosted by G+), and all of the products/services tap into that. If you want that identity to be your real identity, you use a Google+ Profile. If you want to remain anonymous or represent a business entity/organisation, you use a G+ Page. The problem is there's two Google+' sharing the same name: "Google+, the identity system" and "Google+, the social network" and they've done a hamfisted job of explaining what the value of any of it is to the user.
