Like, I could tell you the dragon has 100 hp and AC 17 - but wouldn't it be more helpful for me to tell you that it's trapped in a magic circle of imprisonment? That it is flying overhead while you are hidden from it in a rock cleft?
Putting the point independently of Maxperson: no one disputes that the fiction matters to action declarations in a RPG.
@hawkeyefan's point has been that (i) resolution mechanics also matter, and
(ii) "natural language" descriptions cannot (a) convey the same information to the player as would mechanical information, and (b) cannot convey information to the player that is remotely comparable - in intensity, utility, immersion, etc - as the information that the character in the situation would actually be taking in by dint of their senses and cognition.
It does not refute that point - or to put it more colloquially, is
not relevant to it - to provide an example and ensuing discussion of a GM ("DM 1") who does not narrate any fiction to the players, which is to say who is not really GMing a RPG at all.
