Well none of these mean system generated. Probably they thought that most applications can be surely be closed within a year. And may be a decision was taken in a meeting to issue MRs within a date range because the medical centers are relatively free right now. They know the CEC candidates will consume the Medical slots for those 60 days given to them to file CEC-EE PRs. So, they must have fed their decision onto their system for people with AoRs and the MR was sent out. That does not really make it auto generated.
