I used the rollback function on an edit which changed the category sort key from [[Category:XYZ| ]] to [[Category:XYZ]], but the page remained in the section corresponding to the article's name. I had to do another manual edit to get the sort order back to normal.
note: It would be "nice to have": bug 2098: action=purge and categories - implement a more effectiv action=update or action=rebuild

Seems to be fixed in trunk?
Tested on test.wikimedia.org... seems to work per http://test.wikipedia.org/w/index.php?title=Template%3ANavigation%2Fhome_category&diff=29784&oldid=29783
