Actually, scotus just passed the buck. However, don't over-estimate how much power scotus has. If this audit shows that Trump won the election, the legislature could make a declaration that their previously sent electors were fraudulent and scotus doesn't have much say in it, especially since they have previously chosen to say out.

Now, as to whether the Az legislature will ever do that or what exactly it would mean if they did, is a whole other question. But just because scotus doesn't rule on something doesn't mean it isn't the law of the land. For example, this past election, scotus chose to say out of things (they didn't rule either way). That means if the legislatures start to over-turn things, Trump can in some form (military maybe) just take back power with the legitimacy of these legislatures and at that point scotus will pretty much be forced to stay out of it as that is the president they chose to follow or risk looking like a bunch of crooks.

Regardless of what the implications will be, if it turns out that per this audit Trump was the clear winner of the Az election, it will go a long way to red-pilling people. Not that some will ever believe anything that contradicts the world view they prefer (regardless of whether it's a complete lie) but hopefully enough will.
