Rats, yes, a late-night addition of one when a subtraction was needed.

I'm decades out of date too, so it's apt. The intended audience can
probably discern the message that a broader common netmask doesn't weigh
more than a precisely fitted one which might or might not work as
expected. Fastidious fusspotting on minor terminology matters does not
contribute anything to the meat of the matter, no matter how much it
massages the author's ego.
