Recall that the Supreme Court generally gets to decide what cases it hears and what it’s said about the cases it wants to hear is at https://www.law.cornell.edu/rules/supct/rule_10. It basically boils down to cases where there is a conflict between any two chains of appeals (federal circuits and states). But the Supreme Court is lazy (or smart), so when there is a conflict they usually want to see how other judges think and to see if a majority vote will arise. The cases that get granted are therefore normally just from one of the last circuits to adopt a view (often one of the previously espoused views from the other circuits), and I would need to see the data to believe that there is a bias with respect to whether they adhere to the majority view (if it exists).
My intent was for the statement of their decisions being considered extreme and their decisions being reviewed often to be two separate statements, the former an opinion I've seen often and the latter a statistical phenomenon. The latter doesn't imply the former, but I don't think it would be surprising that the former correlates with the latter.
Is there a strong reason to assume one way or another about whether this will get reviewed by the Supreme Court (and if so, whether it would be upheld)? My understanding is that the Fifth Circuit has become a bit notorious in recent years for its rulings being a bit out of the norm and reviewed disproportionately by the Supreme Court, but I don't know enough about whether this decision might be one of those.
