Does the following answer your question? If a processor emits more than one outbound message per inbound Persistent message it *must* use a separate channel for each outbound message to ensure that confirmations are uniquely identifiable, otherwise, at-least-once message delivery semantics do not apply. This rule has been introduced to avoid writing additional outbound message identifiers to the journal which would decrease the overall throughput. It is furthermore recommended to collapse multiple outbound messages to the same destination into a single outbound message, otherwise, if sent via multiple channels, their ordering is not defined.
