Maybe some copies of the suppressed briefs were circulated before the judge issued his crazy edict, and will eventually be posted to the internet by person or persons unknown? 
Not a chance. From the info available, the gag order was in effect long before the first round of appeals started.
The rules require that the brief be available for public inspection. But the court - my guess - was the one to redact all mention, allusion, hint, or suggestion of the issues. My guess is based on the fact that it appears that the brief's author just went ahead and wrote it like they would any other brief, as opposed to trying to side-step things they knew were not going to be allowed to see the light of day by the public. I've seen other briefs where the author then redacted only the words that were absolutely necessary, leaving articles, conjunctions, adjectives and adverbs galore but nouns and verbs were conspicuous by their absence.
stay safe.
