Apologies if you already know this, but ZFS send and receives in terms of snapshots. When you receive an image, you're receiving a snapshot. When you make a clone, you clone from a snapshot. If you want to do an incremental send of an image (say vmadm send/recv) you want to send it relative to the base snapshot of an image. Our convention is that the @final snapshot represents the base snapshot for all images that are created. That way it doesn't matter what the image is, but we have the same reference point and more importantly the same base for moving everything around.
