I think it’s pretty clear that the redaction machine could have redacted to the exact moment T of death, but that would have been more bother and would likely require major medical intervention to return Bob to health from that state. The fact that it went back further just means that some of Bob’s experience was unwound to time T-X.
If you take a drug that prevents long-term memory formation for 5 minutes, does it kill the “you” that existed in that time? What about a device that reverts your brain and body state back 5 minutes? What if a year later you have just naturally forgotten everything about some 5 minute period? Did the person that existed in that 5 minutes die? If so, when?
I do agree that resurrection doesn’t invalidate the experiment, but for a completely different reason: it was invalid even without the resurrection.
