I mean, it does. And it always has. The executive ultimately has all the power as both other branches have failed to maintain armed forces of their own to enforce the checks and balances.
By my read, this temporary injunction applies ONLY to the plaintiff states - Washington, Arizona, Illinois, and Oregon. It doesn't stop it from being applied in the rest of the country.
Anyone who attempts to enact this will similar be struck down. This is the constitution we're talking about, not a states thing. Anyone being told this the law now can just file for an immediate injunction to a federal court in one of these states, and that order will still apply because... constitution. Literally any federal judge can shut this down every single time.
