Is this AS OK

I was just playing around with attachMovie before starting my project.
How come both my mc’s are animating? Only d1 should animate while d2 should be stagnant at (0,0); isn’t it?


_root.attachMovie("man", "d1", getNextHighestDepth(), {_x:20, _y:30});
_root.attachMovie("man", "d2", getNextHighestDepth());

d1.onEnterFrame = function() {
    _x += 20;
    if (_x>500) {
        _x = 10;
    }
};
