To be clear as I am not 100% sure what you are asking here:

Has your Facebook Fan Page a page off your Personal Profile?  Facebook allows you to have “friends” on your Personal Profile and have people “Like” your Facebook Fan Page or Biz Page.

Anyone you have friended on your Personal Profile – you will see their feeds on your Personal Wall and if you have a lot of friends, Facebook prioritizes the feeds you see from the people you interact with the most – like comments, likes or shares you have done on their posts.

On your Biz Page, if people have “liked” your page, your feeds from your Business Page will appear on their Personal Wall.  Again, if you have a lot of Likes on your business page, those that have liked may or may not see your Biz Posts depending on how they interact with your Page (likes, shares, comments).  You will only see posts friends have made on your Business Page or the shares and likes of your posts.

Whether your friends have liked your Biz Page or not, their posts on their Personal Walls do not feed into your Business Page.  BUT, you will always see their posts appearing on your Personal Page.

Hope that isn’t too confusing…
