I thought the same thing. It seems like the commonly accepted order (Opinion, Size, Age, Shape, Color, Origin, Material, and Purpose) doesn’t include emotion, so that might be what makes it ambiguous.

Or it might be the meaning behind the words - when Bob Ross says “happy little accidents”, he’s not saying the accidents are happy but that they’re a good thing, so this is more like an opinion, while “big angry intents” sounds more like the intents are themselves angry.
