I don't think that's what they're doing, though I admit the language is fairly vague there. It sounds like Magic User is just a wide category that caster classes get put into, not a class unto itself that casters branch out from. It's basically just a useful label that's there in case they ever want to make broad rules or fluff for casters as a whole. I'm not sure it's entirely necessary.
