"Intents and purposes"
for all intensive purpose
Nishi claims it's carelessness, which is plausible. He may just do the body-disappearing after death, which he'd assumed would take place when he made the copy but which never actually took place.

Also he took tae's body, and the point at which he took tae's body was when she already knew about gantz and the black suits etc, so how he revived her with a much older memory (the memory of having never gone out with kuruno) is also a mystery.
That's a better parallel than I think you realize. Sleep is a non-continuity-of-consciousness—there is no empirical means to determine that you existed before you woke up, in contrast to simply having false memories of a prior waking period. Of course this is true always, but most noticeable immediately post-waking.
I imagine dying must be similiar to sleep, you go unconscious, but then reawaken, fully conscious, and it'll probably be instantaneous, so for all intensive purpose your consciousness must get carried on (or at least seem to)
Maybe it is, maybe it isn't. The only person who might know is Kishimoto-1.
The saying that it probably isnt continuity of consciousness is a bit silly considering when we go to sleep, for all we know our previous consciousness ends and a new one begins... so maybe it's not as important as we seem to think.
Really, we need to define "life", "death", and "you" (the general "you", the nature of the individual) before we can really have this discussion. Unfortunately, none of those definitions are easy.
Failure: when your best just isn't good enough.
