There's a standard procedure for when a work wants to use non-standard definition of a term. The rules fit it to the T; the constructions I've given you follow it to the T. That's not obscurantism, that's step one to avoiding it.

That you still keep harping about it, is no different to a medical doctor complaining to an electrician how they keep using "positive" and "negative" wrong. In natural language, words that are written and said the same sometimes still mean different things; most speakers of those languages cope with it just fine.
