Comic Book implies 22 pages on standard comic paper, once a month or some other schedule.
Graphic Novel implies larger single body of work, published once, usually on higher stock with a spine and an ISBN . There has become a larger and larger tendency to collect storylines from comic books together as a graphic novel, which even further dilutes the distinction of the name (and though I didn’t read the quote’s source work, I believe it is one of those situations).
It’s only really a difference to someone who reads them, I guess.
