> The two ‘locks’ are not separate. > The second hash is independent lol

  It seems like there is a misunderstanding on your part. The locks are not separate. You have to open both with the same ‘key’, I.e. the image. From the documentation: “the visual derivatives themselves are matched to the known CSAM database by a second, independent perceptual hash” The “lock” in this case involves one key, and two hashes. If they were separate, you’d be able to ‘pick’ them one at a time with separate keys. You can’t.
