When accessing a menu with Narrator turned on then it will read out the action count in the menu as the number of children. This will be all actions, including separators and hidden actions which can confuse matters as they are not pertinent to the details of the menu.

To reproduce this use Narrator with the menus example and listen for the child count when you click on a menu in the menubar.
