No, the retargetting/stopping happens before you hit the bound element. If 
you move the mouse from over the circle to over the rect you get:

    CAPTURING   mouseout        ex:test2        ex:test2
    AT_TARGET   mouseout        circle          circle
    BUBBLING    mouseout        ex:test2        ex:test2
    AT_TARGET   mouseover       rect            rect

Note that the target is also changed (you can get to the real target by 
looking up the originalEvent object) -- it is possible to tell that the 
event was redirected without looking at originalEvent because the target 
and currentTarget will be the same without the phase being AT_TARGET.
