It makes sense that Google would follow that pattern. First because that is what they have done in the past with Page rank and also back links. They never show what they have up to date. Also there are many trying to figure Google's local search listings and how to manipulate local search for their businesses and clients. It makes sense that Google would want to obscure its methods.
