From Andrew Oxford, Arizona Republic:
Ruled out in the settlement, at least for now, is any work to match the signatures voters signed on ballot envelopes with signatures on file with the county — a process election workers undertake when processing mail-in ballots. The settlement leaves open the possibility for the Senate’s contractors to perform such work if they provide a few days notice.
This is what I am reading, It might be that they’re not in the process yet to getting to the signatures and will notify the “Plaintiffs” 48 hrs before.
Someone who knows what is going on might shed more light on this.
