I think you (and the author of the completion function) misinterpreted
the intended results.  The COMP_WORDS array is an array of the words
on the command line, split as the shell would split them during
parsing.  That's intended to allow function writers to see the words
of the command as they would eventually be parsed.  The second
argument to the shell function ($2) is the word being completed, and
that is as readline breaks the words.  The nature of COMP_WORDS isn't
as clear as it could be made in the bash documentation, but that can
be changed. 

Readline's behavior when splitting words for the completer can be intuited
from the difference, if any, between $2 and ${COMP_WORDS[$COMP_CWORD]}.  That
can give the function writer greater context.
