Ruger Holster Belt Loop: Low & High

What is the difference between the two belt loop designs? 
The two belt loop options allow your pistol to hang either higher or lower relative to the belt.  You can purchase the holster in either configuration and buy the other mounting paddle for $5 if you would like to change the height of the holster.
