No, it isn't related to superko. It has to do with Katago misidentifying the status of groups that are wrapped around an opposing group. I assume the name cyclic has to do with the fact that the groups look like circles. There are images in the paper, but it is a straight forward misread of the life and death status of groups that are unambiguously dead regardless of rule set.
