I'm not saying it was done. The image alone is probably out of
context. I'd venture to believe that someone was able to provide
additional evidence to cause the impound of the ships. As you say,
it's "possible" that the satellite snapped them as they were dragging
their anchor specifically in the area of the cable, but perhaps they
acquired correlating evidence such as a fingerprint from a friendly
military in the area? Military platforms record radar fingerprints and
compile them in databases after visual identification to use as
'unique identifiers'.

My original point was that it's a fairly unimpressive story. I've been
using satellite to do terrestrial surveys for networks and it's not
incomprehensible that someone could take a longshot and call a
company, find out anothers telemetry, call them, and get images
covering a specific time period as you mention. With correlating data
points, it's a compelling case.
