It *does* deliver the messages in the order in which they were sent. I 
was referring to the async case in general: commits from different nodes 
hit the bridge in an undefined order; in your example it could be TX1 
--> TX2 or TX2 --> TX1.

(Note that I mixed up option #2 and option #1 in my previous email)
