Well, it would be kind of argue to argue otherwise seeing as I'd think copying something necessitates having an instance of it in the first place.
However, the downloader shows the intent to make the copy (they are requesting the blocks of the file) and are contributing to the copying (the uploader would not have made that specific copy without the downloader initiating it). I think that would muddy the waters more than enough.
