I was more talking about dual n-back style training, that tries to improve your generalized memory ability. Of course you're right there's another way to look at it, but it's basically the difference between crystallized and fluid intelligence. You know more about Brazilian Jiu-Jitsu, but you wouldn't say your IQ has increased due to that. Now that I'm rereading the passage, it seems the author was proposing a method of loci type approach, which is great for memorizing specific things. But not so much for general working memory OR for gaining domain-specific contextual knowledge that makes your current working memory more effective. And not sure how it relates to concentration. Sort of a fuzzy paragraph, much like the rest of the piece.
