AC on "CNN Biz Break"?

I'm currently watching Paula Zahn Now and Anderson Cooper just came in after a commercial with a "CNN Biz Break". Does he normally do this? Seems a little strange, but I don't always watch Paula so it could be a normal thing. One would think that a CNN Business News correspondent (Susan Lisovicz, Valerie Morris, Carrie Lee, Kitty Pilgrim, etc.) would do something like this.
