I can't read the whole article but at least with the two paragraphs shown the text does not match the headline.

The headline mentions parallel universes but the text is discussing the implications of an infinite universe. Which, I believe, are different things (though maybe they are connected in the full article).

Since you raised it, though, I'd be curious how parallel universes (and which theory of them) would explain PLR? I don't konw where deja vu comes in, having experienced it many times myself I don't find it to be all the bizarre and requiring extraordinary explanation, any more than a mystical explanation is required for the fact that if I stare at stucco long enough I can find faces in it (the human brain is so inclined towards pattern recognition that it is easily fooled into seeing patterns where none exist). I don't know what "connections" with people means.
