Based on the previously posted definition of a "Non Final Action", it's difficult to know to whom this action was mailed.  That definition lists the "applicant" and says unless they respond within 6 months the application will be abandoned.

IMO, that can be taken as the applicant for the re-exam and if they don't respond within 6 months, the re-exam will be abandoned.  In this case, perhaps the settlement contains a provision where the J's are going to withdraw their re-exam requests.

However, the "Non Final Action" most likely can apply accross a spectrum of USPTO applications, so by applicant, the definition may be more generally referring to a person applying for a patent.

Hopefully, there will something posted in the documents area that will show who that got mailed to.  That might reveal something important.
