They're not numbers, they're people. They're neither "equal" nor "opposite". What they are is very similar, with some differences.

I guess if Magic Land recognizes them as two versions of the "same" person, as in labeling them both as Tom Riddle, you can play that game. I've seen some comments here or on reddit to that effect, but they seemed snide comments about confusing the Atlantean operating system. The snideness would be appropriate, IMO.
