I translate that as:
the receiver (verifier) has evaluated a certificate loop for the sender
(prover) once and derived a certificate result. The verifier then could
have kept the certificate result cached until it expired, in which case the
sender didn't need to send it again, or returned the cert result as a CRCert
to the sender, in which case the sender is acting like extended memory for
the receiver (ala cookies).
Right?
