If I remember correctly, it's because it will be more complicated if their performance is amazing. If they are amazing, they will have to win or at least place - if they win/place, people might think it's unfair and that some cheating happened because of the scandal. So, the judges doesn't really want them to win because of the backlash. So, better for them to be not good so they don't have to face the dilemma.
It’s been a minute. Can someone please remind me why that guy didn’t want their performance to be anything noteworthy? I really hope this gets another anime season!
