I can't edit anymore but I misunderstood the second layer. The second layer contains a single Secret Share (that can be used to reconstruct a decryption key after certain threshold) and an encrypted image information. User must upload multiple photos matching the initial CSAM database past certain threshold for any of them to be decryptable at all.
