You're correct.

In another blog post where he uses "shibui" as an example of an untranslatable word, he says, "Saying shibui like that, in a mere second, conveys what would otherwise make a clunky and unnecessarily long digression."

At the root of nearly all the blog posts like this one (basically explaining why they don't agree with a widely held belief) is a redefinition of a term or word into something very specific that contradicts the common definition.
