I would agree that these are not the same Image, it might be the same location and possibly the same photographer but there is a shift in the jacket folds / pose, so it is likely to be two different frames / images from the same set, how often do you get Images that look the same, as the model and photographer only moves slightly
As you Licence a specific Image and not the Image and all variants / similars, there is nothing really wrong, the photographer may have uploaded similar images to two different sites, or would that be legally wrong?
