I don't have anything to add theory-wise to what this might represent but…

Where the mid-latitude areas fit specific ISS ground tracks for Aug 9 and 10, the Alaskan zones match the tracks that the ISS will follow six Earth circuits and about nine hours later.

It's something to think about but I'm not sure it takes us forward.

It's possible that someone has been conducting paper exercises and their dummy navigation warnings have got into the public domain.

Regarding the Starlink connection, the zones are much better matched to the ISS 51°.6 inclination than to Starlink's 53°.
