You missed what is really going on. He just doesn't see this as a legal issue. He already established that with the first ruling when he redefined "fine" as "tax". His position is that he won't override (the medicaid expansion nothwithstanding) what Congress passed as he doesn't see that as part of the job description. He has already essentially said the American people opted for this at the ballot box. This is the second time that the actual wording of the law has not been of consequence. Clearly SCOTUS doesn't feel obligated to act stricly as a legal court anymore and views their role as being more pragmatic.
