Not quite, at least in the AMQP case. Publisher need not be aware of binding key also. There is explicit concept of 'routing key' and 'binding key' in AQMP. A message is published in the exchange with a routing key. Its broker responsibility to match the routing key of the message with all the binding key's associated with the queues. If there is a match of keys, then message is delivered into queue.
