Comment (by aaroncampbell):

 Thea reason it isn't canonically redirected is that when it finds that the
 category is NOT one of the post terms, it uses `get_permalink()` to
 generate the URL to redirect to.  Since our filter applies to that URL as
 well, toward the end of `redirect_canonical()` it checks `$redirect_url ==
 $requested_url` and returns false instead of redirecting.
