Very observant. It was acutally a lazy programming thing on my part that has a side effect of moving around names on the list sometimes. Here's hwo it works:
I have a list of names: (1)Alex, (2) Steve, (3) Bob, (4) Brian, (5) Joe, (6) Chris.
With the list, it's easy to change the size (increase or decrease, from 6 to 7, for ex) and its easy to change the contents of a list item (change #3 from Bob to John).
However, if I want to remove "(2) Steve" from the list, I have to copy #3 - #2, then #4 to #3, then #5 to #4, then #6 to #5 ... and THEN make the list only 5 long.
What I did instead is, if I want to remove "(2) Steve" from the list, I just copy #6 to #2, then shorten the list to 5.
