I actually puzzled over this a bit when I first realised that Second
Life's pie menus worked this way. Originally, the pie menus worked
well when you didn't click too close to the edge of the screen but
didn't actually open under the mouse cursor if you did. Since the
"More..." item is sensibly always the southmost one, opening new
submenus centered on the mouse would cause the pie menu to drift down
the screen until it hit the bottom and caused problems.

Also, opening the submenu at the same location has the nice
side-effect that the mouse remains over the "More..." option for the
pie menus that are nested 3 or more levels deep.

What I have been contemplating is how to make it possible to open the
next layer of a pie menu without moving the mouse at all. Sadly, it'd
probably break too much from normal UI conventions to be worth doing.
