It is true that the issuer is unable to discover that double blinding is being used. The real problem with the protocol is that it requires payor/payee collusion, which may make it difficult to execute.
Can the payee discover that the payor isn't colluding before the bank can figure out who the payee is? -Allen

Of course. 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.
