With the modified protocol the payor has no choice in the matter. It's a case of giving the payor a blinded unsigned coin and demanding he get the bank to sign it - if he doesn't do this the payee will notice immediately. Even with payor and bank collusion there is nothing that can be done to identify the payee.
