I think you will get rid of the confusion by using the drop-down menu located next to “Home” link at the top-right once you have logged-in.
Then, use the “Use Facebook as Page” option and that is what the Fans will see- the wall of your fanpage.
Otherwise, you are simply viewing the wall of your personal profile. Hence the difference.
I hope my reply does not confuses you further, lol.
