There is certainly a fine line about when and what to comment.

In this case the code is so baroque that it really deserves a comment
or you'll get people trying to fix it when it ain't broke ;)

Either that or as you suggest, re-work the code to make it more obvious
about what's going on.

Now which patch (adding a comment or changing the code) has more chance
of being accepted?!
