The panels I've brought show the YM not adapting to the snakes going over the top, meaning it's not countering the snake attack. If it lived up to the "legendary argument of doing what the legends say" that would not have happened. So, the only logical conclusion would be to say that so called "legendary items", don't have credibility simply for being called legendary. Which would also fall into the category for the TB.

Btw @Jason, the anime further proves my point, and doesn't show the YM expanding.
