Thanks for the explanation.

Just re-read the spec, like Ben suggested:

<field name="auto delete" type="bit">
     auto-delete queue when unused
       If set, the queue is deleted when all consumers have finished
       using it. Last consumer can be cancelled either explicitly or because
       its channel is closed. If there was no consumer ever on the queue, it
       won't be deleted.

It was the last sentence of the <doc> that makes the difference: "If there was no consumer 
ever on the queue, it won't be deleted." So technically speaking, this field is not 
"auto-delete queue when unused" but "auto-delete queue when no longer used."

Thanks again!
