Suppose that there's a really iconic pic of George Clooney eating a burrito in Times Square, with a "Getty Images" watermark on it, in the training set. It's perfectly framed, has a somewhat comic expression, and a bit of the contents spilled on his shirt. It seems quite possible that the model could produce an image that isn't identical to this but so much so that people assume it's a copy, maybe produced by an artist based on the picture. Worse, it will have most of the "Getty Images" watermark right on the image. If that doesn't convince you that there might be an issue I'll just stop here.
