Why does the list of friends on the new facebook profile always show the same couple of friends?

I've been wondering the same thing all evening!! This is what I've found so far, this is straight from facebooks help page:
"How does Facebook decide which friends appear on my profile?
Friends who you publicly interact with the most appear first on your profile. Examples of public interactions include Wall posts, comments and mutually attended events — Facebook will never show friends based on whose profiles you choose to view or who you interact with over messages and chat."

Not so sure if I believe that based on what I've seen so far.. I do feel like who you view and interact with are influenced whether they admit it or not. Could be wrong though, I have no idea.. this is the closest to coming to an answer I've found so far...
I don't like that it continues to show the same friends over and over rather than being more random.
