As I understand it, probably.

SCOTUS just made a huge power grab, in the guise of sending power to the lower courts.
But none of this that gets to the lower courts is going to end there. This is a new, untested precedent. It will be appealed up to SCOTUS whenever the first case that comes along tests this.
SCOTUS will then rule whatever the hell they want, since they gave themselves the power to do so.
