"Super Jump Install:
If you cancel super jump prejump frames with a special move, you retain super jump properties (e.g., gravity) when you return to an airborne state."
The first 2 recordings demonstrate the gravity changes allowing both j.K j.D, and j.H, after SJI Fuujin~Hop FPRC, as the install can be carried into rekka followups. j.K j.D is the only known way to double overhead during Issokutobi FPRC and is -2 on block, whereas j.H is +10 or greater on block.
The last setup demonstrates the superjump turnaround being used after Kou, allowing for an ambiguous (but mashable) left/right setup based on how long Kou charge is held. Without SJI, air buttons after Kou sideswap simply whiff.
