If you can keep the person within different areas of the screen, for example have the talent dance in each of 4 vertical non-overlapping sections of the screen, then use garbage mattes to combine the 4 shots. Just make sure the lighting and background do not change from shot to shot – also may want to set the camera to record and not touch it at all.
If you want more than the number of occurences of the same person in a shot, and have some overlap, you might try this – although Premiere might not do it:
Position some rectangles of green material behind the talent, in the overlap sections of the scene. Then once you have recorded the “foreground” shots, position your talent in front of the green, then with the positions set, remove the green, and get the shots. Then, assuming the camera has not moved for any of the shots, use AE to key the background shots into the green areas, thus having overlapping actions, without completely compositing every shot.
Don’t know if that would work, but might be an interesting experiment.
