Correct but other Circuit's could take it up if they get enough extremist judges to do so. The Supreme Court in their VRA rulings laid out a road map to essentially make the VRA's protections irrelevant.
This case is an example of the profound way the judiciary is breaking down. In this case, the District Court read the law as it's been read for 50 years and said the map is illegal. The extremists in the 5th Circuit essentially overruled them. They composed their rationale using the breadcrumb trail of language the Supreme Court blessed in their recent VRA rulings. In other words, the Supreme's have essentially created the room for states to gerrymander by pretending the lines aren't racial and simply political. The District Court tried to frame this as a racial gerrymander and the 5th Circuit essentially used the Supreme's own language to pretend that part of the ruling away into the Texas/Louisiana swamps.
In short, it's regional for now but other regions can (and eventually will) take this approach up to racially gerrymander with the Supreme Court's blessing.
