Your question makes it sound like you believe it succeeds, but the answer you pasted is incorrect. As for why it fails, it is likely a bias arising from the question being way more commonly asked in the corpus with equal mass than with distinct mass, increasing attention weights towards an answer expressing equality. I believe current LLMs lack some common sense at an architectural level. They learn both specialized facts and general deduction in the same weights class: in my mind, they should separate their world model from their instance model.
