The quote continues:

"about the [horizontal] size of the letter "M" in the current font."

which apparently wasn't to your liking.

And still, as I said, the typography books I've consulted
(publiched in the 1990ies), also refer to "em" as the width of
an "M".  The "(nominal) square" (or however one should translate
the term "fyrkant", is bigger than an em, so calling it 
an "em square" is a misnomer.  Though quite expectable
given the flora of different definitions of "em".
