In one sense, it doesn't matter because it doesn't change how the game mechanic works. In another sense, figuring out what hit points "mean" helps the DM flesh out their narration and keep it consistent. And even if that's an intangible, it's still an improvement to the game.Yeah, to be honest we never really sweat what hit points "mean" and I suspect most tables are the same.
Well, it might not be entirely intangible if the DM doesn't like to make game mechanics transparent. I've been frustrated in the past by ambiguity between an attack narrated as a minor surface injury because the target had a lot of HP and because they had Resistance to the damage type. If the DM doesn't want to just show their cards when it comes to game mechanics, clarity and consistency of narration is essential.
