He could have have done all you said for the throw, but from the video I really can't see anything out of the ordinary.
Also reminds me of why I stay away from WEKAF Armour.
I also have issues with wearing armor. I prefer the Dog Brother's style approach. You respect the stick that way. Shawn and I became fast friends and training partners when I first came to Ohio. We did this by using no armor and light bamboo sticks. Our bout lasted 35 seconds.
I really cannot comment as to why you cannot see how intricate that kote gaeshi was. Perhaps is was just the camera angle... But for the opponent to debrief with me that he believes he tripped speaks volumes. I was very proud of Shawn's growth in Yanagi principles of martial technique.
