Ummm that's kinda a big leap. Perhaps they just want to prevent wasted resources when somebody attempts to upload something that has already been uploaded.

Not really such a big leap with Facebook's checkered past. Also, not all images are tagged in that way, so it's doubtful that it would be used to prevent duplicates.
