If that's the same or similar to the earlier clip, it's science fiction - it can't happen in quantum 'Many Worlds', and there is no scientific multiverse hypothesis where it could happen. You can only pick and choose which parts of a scientific theory or formulation to ignore, and which bits to add magical stuff to, in fiction.
If you want to believe a fantasy explanation for your very ordinary memory failings, that's your concern; but if you claim support from a scientific hypothesis, however speculative, you're fooling yourself if you think you can just break the rules to make things the way you want.
