Yes that's potentially why it's already fixed now in some models, since it's about a week after this actually went viral on r/localllama originally. I wouldn't be surprised if most vendors run some kind of swappable lora for quick fixes at this point. It's an endless whac-a-mole of edge cases that show that most LLMs generalize to a much lesser extent than what investors would like people to believe.
Like, this is not an architectural problem unlike the strawberry nonsense, it's some dumb kind of overfitting to a standard "walking is better" answer.
