Need to know what these Module Positions do? ie. Leader Board Module

Hello,

Please see short video: http://www.easywebvideo.com/e80f61de

The video will show you exactly what I am trying to figure out.

I was wanting to remove the "Leader Board" view on the registration page for non-registered users. I figured out how to remove the view by setting "Leaderboard (Public in es-dashboard-sidebar-bottom)" to "Registered" and not "public."

But what is the other module used for? "EasySocial Leader Board (Public in )", I found that any updates I make there don't do anything in Easy Social. So why is it there? What is that used for?

Thank you,

Ron
