I think Jorge is confused by the use of the name 'JYJ'

They used JYJ under avex in Japan, but they are now also using JYJ under CJeS in Korea. CJeS is the company avex doesn't want to work with and therefore dropped JYJ. Matsuura is sad because JYJ didn't choose for avex, but JYJ had already recorded their English album and I'm sure the plans for release and their world tour (showcase) were already made. It wouldn't be fair to just drop CJeS (and the album they worked on in US with Kanye West & Rodney Jerkins) for avex.
Like someone said, even if Ayu was there and represented avex and Matsuura, she would have loved to go anyway

I think she was sad that she tweeted that she couldn't go to their Thanksgiving live, because she was performing herself. And she also tweeted that she wanted to visit Korea, so now she has been to Korea and has seen JYJ live

JYJ fans are so worshipping Ayu right now
