How The Kill Screen Affects DI vs Attacks/Throws

>"I don't know why this happens [...]" I do happen to know!

What is di?

what about holding di in the entire time? does it not apply unless you release and then hold left at the right time?

Kill screen has a ton of weird stuff like bowaer down b will sometimes hit the Shockwave as well and override the strong hit but ONLY during kill screen. It cant really happen during normal gameplay
