Wow this is an excellent find and it sounds right. They had something as arbitrary as "pets.example.com" counting for "www.example.com" so then "blog.example.com" should surely be the same as "www.example.com" and "example.com"
After reading some of the comments, it looks like this only counts for tracking inside of google webmaster tools. It doesn't necessarily mean that this is true for page rank and the "google juice".

Can anyone clarify?
