Well that's the point. It's an informal term. It doesn't have a specific, overriding definition. The words mean what the words mean, and "HD remake" means "a high-definition remake". That's what it's always meant, and a group of people deciding they couldn't be bothered to think of a more accurate term for games without new assets doesn't mean we should enshrine their mistake as part of a cliquish lexicon.
