then why would sasuke still ask "when did he activate izanami"? if kabuto was "affected" the moment itachi used the technique then kabuto should've fall from the top after he stabbed itachi and won't end standing there.So according to itachi, he used izanagi at that 1 moment, so it really does not need pre prep time?
After that events were basically recorded , He talked with kabuto a bit trying to change him, then put him in the loop? iS That what happened?
I still think the jutsu was "in effect" from this moment:

It would make much sense this way- itachi began recording the event when kabuto stabbed him, then from the page I link here, that's the time itachi "showed" the "recorded event" to kabuto. that would explain why kabuto was left standing there.
