I've discussed this with one of our global mod and the answer is Yes, the pictures in the file is irrelevant.
We based our dupe on the file size (exact size or <10%difference) and file format.
That's the most fair and logical application of the rules, thanks for clarifying, K!
And I would add... If you have a duplicate clip and, say, 20 or more high-res pictures, then don't post the dupe clip, but DO post the images as their own upload.
I'm always happy when I can "match" a clip and the related photo shoot, then create my own combined folder.
