Comment (by SergeyBiryukov):

 This is consistent with how `wp_update_post()` works.

 `mw_editPost()` fills in `$post_category` array ([source:tags/3.6/wp-
 includes/class-wp-xmlrpc-server.php#L4507 line 4507]), then passes it to
 `wp_update_post()` ([source:tags/3.6/wp-includes/class-wp-xmlrpc-
 server.php#L4571 line 4571]). `wp_update_post()` only overwrites existing
 post categories if the passed array is not empty: [source:tags/3.6/wp-
 includes/post.php#L2919].
