Speaking as the first close-voter1, I agonized over this one.
Ultimately, I decided to vote to close because I felt that KutuluMike's answer to the newer question was more complete. I particularly liked the mention of the supplemental materials, which I felt was missing from Null's answer to the older question, and most relevantly the observation that Neo isn't the first "One" that Morpheus has tested out2.
At this point I'm also going to refer to our previous (and, I understand, not-uncontroversial) discussion Should we always close the newer question as the duplicate?; I don't believe it's necessarily the best option to close the newer of two questions. Others may disagree, but that's my stance.
Should it have been closed at all?
This section is mainly in response to Null's comment on this meta question:
They're not duplicates -- one asks why Cypher said something, and the other asks if the crew kills potential Ones.
Okay, mea culpa: there's a subtlety there I hadn't considered when I cast my vote. But I do still think they're intensely related questions, and my gut reaction upon reading the older isn't "What is Cypher's motivation here?" but "Is Cypher saying they're literally going to kill him?"
That being said, I do appreciate that another perspective exists. I stand by my vote, but I'm not going to throw a tantrum now that it's been re-opened.
1 Though I will point out that I voted from the queue, so I didn't make the initial determination
2 I would have liked the answer a lot more if those materials had been quoted directly, but that's a different conversation entirely
