Taiwan's defense is the defense of the Senkaku Islands and is synonymous with Japan's.If China maintains its maritime routes from Japan to Taiwan, the Philippines, Indonesia, and Vietnam, it will not be able to enter the Pacific Ocean and will only be able to develop strategies from the west.

Moon Jae In Korea is pro-China.Even if Korea joins forces with China, China will not actually be able to enter the Pacific Ocean.In this sense, Korea and Taiwan have different strategic meanings on Quad.

With this in mind, Moon Jae In is not flying around like a bat, but is moving in a way that you don't really understand if you don't say you're going to be left behind unless you don't actively participate in Quad.
