The error here is that people are (mis)using the word "copy" when they
mean "instance" or "instantiation."
The original of me (i.e. me here and now) is an instance of me; any
effectively perfect copies of me will also be (at the moment of their
creation) instances of me-as-I-was-when-scanned.
Bearing this crucial distinction in mind, and changing the rules so the
torture can also be a risk for all the instances (since that seems
important to you), the probabilities are actually 1/1,000,001 and 1/3
(since you stipulated a million copies versus two copies).
