The Swan Roll was my first two handed norsaq roll. By two handed I mean two norsaqs, one in each hand. This is not two hands on one norsaq. I suspect that this roll has a practical purpose if your paddle snaps in two at the loom and you need to recover. This is a fairly powerful forward finishing roll. You should be able to make this work prior to attempting your reverse sweep and forward forward norsaq rolls.
You can view the video and tutorial here.
