If I’m reading that excerpt right, it sounds like the judge isn’t going to order USG to provide clearances until and unless he gets to see the expected Brady Material?

If Brady Material shows exculpatory evidence, then I’d think the judge would consider tossing the case, obviating the need to give clearances to Sidney Powell.
No sense in ruling on the security issues, then picking up production obligations and dismissing the case.
The order of taking up is just the more efficient order of dealing with issues, based on the range of remedies the court has available.
Sidney Powell's Motion to Compel Production lays out that the judge could reasonably boot the government's lawyers from the case, after which point the security issue could be resolved too. If the government lawyers are booted, the case gets another long delay.
Many different outcomes possible - judge could deny motion to compel too, and swiftly move to deny security.
