I don't think they're describing Baader-Meinhof illusion, instead it sound like the phenomenon I know as "Feynman's grandmother" whereby we credit a coincidence with a degree of magic because we fail to notice the frequency compared to non-coincidences.
The phenomenon plays out something like this: If you recall all the times you read something, and the subsequent article has no unexpected relationship in key concepts then you'll see it's just a normal statistical occurrence rather than something spooky and notable.
I think he's actually describing a much deeper phenomenon called a "coincidence" in which two things occur which are related in some way other than by causality. This strange phenomena is usually attributed to a concept known by the phrase "chance" which is deeply rooted in probability theory, but top scienticians and psychological probability computationists are still studying this mysterious phenomenon.
It is the Baader Meinhof Phenomenon[0] or frequency illusion[1].
