Yes, your analysis appears correct. In all likelihood the program is
working as intended. Clearly the man page does not match the actual
behavior as the very first sentence says "...appends their contents to the
PATH...". The man page says nothing at all about the sequence the
directories appear being changed. And while the man page goes on to explain
that the "default PATH ... values are obtained from /etc/paths..." that is
misleading. The use of the word "default" implies to me that if the current
PATH already contains those directories the existing PATH will be used as
is.

Yet I think we can all agree that the man page is crap and the design of
path_helper is crap :-)
