So, unless I'm missing something, the former comment appeared correct.

There's no indication in the docket that anything about the case is still live.
If you read the original brief, this is what it requests:
> Petitioners also ask the Court to consider this Application as a petition for certiorari, grant certiorari on the questions presented, treat the Application papers as merits briefing, and issue a merits decision as soon as practicable.
In denying the application, it is by proxy denying the request for certiorari, although I believe it would be theoretically possible to actually reapply for certiorari. (Looking through SCOTUS's rules, it does seem that Rule 22.4 suggests that this is the case)
And yes, I did look through SCOTUS's docket to find any other docketed case referring to Kelly v PA.
