No, he means that the OP has a cropped version of the image and the “counterfeiter” has an uncropped version of the same image.
If the counterfeiter really stole the images how could he have a less cropped version.
Maybe Amazon also sees things like this and decided they can’t tell who stole from whom.
I don’t that is the case here but it is possible Amazon gets all sorts of notices like this from people who aren’t as genuine and may be lying to remove a competitor.
