I'm in complete agreement on the questioning of these descriptions/ideas.
IF you only refer to strokes differing to the extent of hinge actions, I believe you must say angled produces higher trajectory than horizontal (lay back associated with angled; no lay back with horizontal).
Other differences must be referred to in order for the ideas to "hold water" (such as ball postion).
Maybe the differences are implied and I'm missing them.
