Indeed. The 55-60 is for columns of actual text.
That leaves up to 25 columns of indentation in an 80-columns window.

So, ~8 columns of indentation, which leaves ~72 columns of actual text.
Since most lines don't extend all the way to the 80th column, that means
most lines stick within the 55-60 optimum.
