If you chose "Add selected authors" to your user category, then yes it will add one "Tom Clancy" entry to your user category (not 20). If your seletion covers multiple authors, it will popup with a dialog asking which you would like to add in case you wanted only a subset of them.
@ntome - this plugin has nothing to do with renaming directories. It is simply about adding/removing/viewing items in your own user category lists in the tag browser on the left of Calibre. It does not change the books themselves in any way.
