Why is it that…

```auto

onClipEvent(mouseDown){
     x++
     trace(x);
};

```

has an output of:  
1  
2  
3  
4  
etc.  
based on the number of times you click the mouse.  
However…

```auto

onClipEvent(mouseDown){
     x++
     this.duplicateMovieClip("newMC"+x,x)
     trace(x)
}

```

has an output of:  
1  
2  
1  
3  
1  
4  
1  
1  
2  
5

after 5 clicks. Why is that?
