Context. She retired from women's competitions to play against stronger opponents. Here, she was paired seven times against women, and there's no way that was accidental. At least I don't believe it, and clearly she doesn't either.
Why wouldn't it be accidental? Ketevan Arakhamia-Grant played six women. Throwing a game because you would have preferred to be paired with other opponents is very strange. She can't expect to pick her opponents by herself, and why on earth would anyone stop her from playing men by tampering with the pairings? She must have a very low opinion of the organisers.
