Loading 2 swfs into one file. to display side by side

This was super easy using AS2. I had 2 ‘loader’ movie clips placed on the stage and simply used the loadmovie to bring up the external swfs.

How would i accomplish this using AS3? I simply need one movie to display on one side of the stage, and another on the other side of the stage.

do i still use these ‘loader’ movie clips?
