Starting by the glass orb in the second video.
b2,2, ts~1, ji2, f1,3, 112, d2, gun shot, 11, ss mixup is here nj 2( which lands on other side, that shit is hot <3 shogun, consider it stolen) then 2, u3. You can also do 123 after the nj2 to put them back in the corner, I think the reason he did 2, u3 is because like the raven he didn't know what side he'd land on.
I've noticed it happen sometimes after a hard knockdown into ss pressure, if you time the jump as they're standing you can land on one side or the other. Not sure, haven't tested take with a grain of salt.
After further tinkering, I actually think its the SS itself that creates the crossup. try doing d2 to a character in the corner, as they fall do ss (late enough so you don't actually cross them up with the SS and land on the other side, it's hard to describe. notice how harley will be on top of the other character. from this point you can choose b2,2 or f2, or nj2 i'd imagine. each with a different outcome, if you jump you're pushed to other side as they stand. It's really weird/neat
