The transaction is not supported across the wan sites. If inconsistent state occurred due to a network problem between the wan sites, the inconsistency would exist during the network outage. However, once the network problem is resolved, the wan gateway would resume sending the events again. Two sides would be eventually consistent.
The persistence and redundancy mentioned by Anil would be useful if the senders are down (HA scenario).
