Posts from FB Business Page 'A' to show up on news feed of Business Page 'B'?

Hi - wondering if someone can shed some light on this for me.

I am the admin of both Facebook Business Pages A and B.

On Page B, I have added Page A as a favourite. Page A shows up as one of my 'likes' on Page B.

When I add a status or update on Page A, why doesn't that post show up on Page B's Wall?

Thanks for any help you can give!

Both walls are completely separated and independent from each other.

Page A's posts should display in Page's B Home Page but not on its Wall.
