Slide 10 and 11 look like elbow plane - I will have to check other video to confirm. Certainly has great balance and touch.
I saw elbow plane coming at his take away. Pretty obvious if you observe the #3 accumulator angle. No other practical way to get there without a bunch of compensations and this man doesn't have many.
