It doesn't have a way to tell it which one to match if multiple match. It just 
takes the range that you're looking at and the list of elements and/or ranges 
that the first range might start with. It has to have a way to decide which one 
to match when multiple match, and the most efficient (and easiest) way is to 
match the shortest. So, that's what it does.
