The SCOTUS did not over turn the injunction, they stayed it’s implementation pending appeal. If there is not appeal or if the writ is denied the injunction becomes active again.

Don’t know. Different case, different jurisdiction, different plaintiffs and from what I understand different legal arguments.

You response indicated that you thought the SCOTUS has issued a binding decision in Trump v. Sierra which would have been binding nationally. Not the case, this case is in a different circuit and the legal arguments may well be totally different.
