So the Bijuu breaks his own genjutsu, then breaks their genjutsu? Do you realize how stupid you sound?The Bijuu breaks it by Chakra, so your refute is invalid.
How is it beneficial to have a Bijuu break 2 genjutsu before you can break 1? Kakashi could not break Tsukuyomi in the 3 days he was in it. A Bijuu isn't going to do any better.
