I was totally with it until the nonsensical theory of personal identity we get in the last 10 minutes.
On this outcome, joe survives to a lesser degree than he does if he had just died originally. He then would have joined his parents and continued a chain of psychological continuity from his mortal life. What ends up happening is a diminished version of what Parfit calls “fusion.” The person who survives at the end has some links of psychological continuity with joe but they are very minimal, and many more links with the boxer whose body it is. And now when that person dies the person who goes to the afterlife is joe to a lesser extent than if Mr Jordan had never intervened.
