Random stuff leaves a different sort of mark unless it's the first pass through the press. The fisheyes that are fairly common are from random stuff in the press. I'd think something damaged the plate, or there were two plates. Either is possible, they could have easily run two presses to finish a print run in a hurry. The plates wrap tightly around a steel roller, so the sort of damage that would cause a gap like that is unusual.
