Unless I'm mistaken about which lines you mean -- I don't have all the
patches applied, so I'm inferring line numbers by looking at the diff and
my own source file -- those lines implement the insert-unambiguous style:

insert-unambiguous
     This is used by the _match and _approximate completer functions,
     where the possible completions may not have a common prefix so
     that menu completion is often the most useful may of choosing
     completions.  If the style is set to `true', the completer will
     start menu completion only if no unambiguous string could be
     generated that is at least as long as the original string typed by
     the user.  Note that the _approximate completer uses it after
     setting the completer field in the context name to one of
     correct-NUM or approximate-NUM, where NUM is the number of errors
     that were accepted.

Do you have insert-unambiguous set to true?  If not, perhaps you should.
