If it's two different pickups the demo ought to be focused on one pickup, then submit another clip. It makes sense as it is more focused and choices on pickups can be made more easily. Plus you could link the other pickups you used and your other videos that could present that pickup better.
However if you're just focusing on a one pickup, it might be very bland if it's just rhythm, or just a lead and with a lead you'd need a rhythm anyways so I dunno how to manage that.
