That depends on your window manager.  If I do the same command, I get 'top 
equal to 124, as the title bar is 24 pixels high and the window manager 
(Compiz) puts the top of the title bar at 100.  Other window managers may 
choose to put the Emacs window at 100 and the title bar above that.  It isn't 
defined what a window manager should do.
