Swing In and then Reverse Transition

I'm trying to create an effect where a clipboard swings into view on top of another clip, partially covering it, and then swinging back out in reverse to the way that it swung in.  The clipboard is a PNG image file with a transparent background.

I have successfully created the Swing In effect using the Swing In transition as follows.  The clipboard swings into view as if it were hinged along the right-hand side.

At the end of the Clipboard clip, I want it to swing out in the reverse, again hinging along the right-hand side.  However, I just can't seem to make it work using the Swing In or Swing Out transitions.  Is it possible to do what I'm trying to do?
