The "nod if you understand" bit doesn't really mean anything here, because the model will simply generate a response that fits what it's generally read before. That means you can pretty much expect it to nod and say it understands. It doesn't.
Forgetting formats is something it does over and over again. I tried wrestling it into generating a genuine guitar tab. Same sort of inconsistencies. I wouldn't read too much into forgetting quotes or emojis and stuff like that. It also forgets that a 7th chord still needs the root, third and fifth when illustrating them. Sometimes it forgets it needs notes at all!
