IMHO that first waza is pretty gross manifestation of bouncing uke. Its setting up intent to reflect uke straight back and up. Its an application of what should be hiriki/kokyu IMO. The "reverse" downwards thing is essentially the same, I'm pretty sure.
So are you saying you actually took this waza from Shishida? What did it feel like?
Yeah, sorry, forgot to reference Shishida's name on the quote
