The exchange (broker) does not use the subject at all for it's routing as it's not there in AMQP 0-10 (the protocol uses routing key for this). The subject was introduced by the new addressing mechanism and is Qpid specific. (I believe in AMQP 1.0 the subject is in the protocol itself and qpid.subject will map directly to that - however I stand to be corrected).
But for now "qpid.subject" remains a Qpid specific property used by the new Qpid Client API (and also JMS). The doc sort of explains how the qpid.subject maps to the AMQP 0-10 protocol - perhaps that section is not clear enough?
