I guess they respected their own recommendations: "when you're trying to illustrate what a hyphen looks like" was not one of the recommended uses of a hyphen!

I should also note that this whole point seems at best a point for typography geeks. These are three almost identical marks that have very similar uses. I am completely convinced that no one has ever disambiguated a phrase by noticing that something is a hyphen and not an en-dash or vice-versa.
