Yeah, I remember the same thing from Fred's book. Basically if the bow had a high grip and was designed to be shot with a high wrist/loose grip he considered it to be a recurve whether the actual limbs had any recurve or not. Conversely if the bow was designed to be shot with a low wrist/firm grip he considered it to be a longbow even if the limb tips did have recurve. I'm not sure everyone would agree with him on that though. It can be kind of a gray area with all the different bow designs.
