Its a fundamental rule in the way xTalk string lists work.

It is neither a bug nor a feature - it is a rule - much like xTalks are 
one-based rather than zero-based for indexing.

There is no bug about it because it is not a bug.

Trailing delimiters in LiveCode (xTalk) string lists are ignored. If you 
want to express an empty last item in a string list you have to append 
an extra delimiter. i.e.

   the number of items in "" == 0
   the number of items in "," == 1
   the number of items in ",," == 2
