I think I'm beginning to see your point. If you perform the second operation first then solve and use counterclockwise rotations they work. I wish he'd made that clearer.

Thanks for commenting. But Devlin states that v and w are indeed clockwise rotations of 120° and 240° respectively since rotating an equilateral triangle counterclockwise 120° is the same as rotating it clockwise 240° and vice versa. By the way, how did you solve x ○ y = v assuming that the...
