I think it's just Yoda's plain Jane (but brilliant) good old RFT as per he teaches day in day out.
Yoda's motion is just incredible IMO. I could watch that driver video all day. I'd love to see him put up a load of footage of himself hitting various shots from various angles, including driver, full irons and 3/4 wedges. I had never seen a swing anything like his prior to seeing it for the first time.
