[jboss-user] [Clustering/JBoss] - Clustered local interfaces? Really?

I ask awfully lots of questions recently but bear with me. I found something truly weird. I wanted to see what happens if I declare local interface as clustered in jboss.xml. I did not expect that it would work just like remote. Does anyone have an explanation?
the only thing which is different was logging. At startup JBoss told me:
[org.jboss.ejb.StatefulSessionContainer] *** EJB 'WorkAddress' deployed as CLUSTERED but not a single clustered-invoker is bound to container ***
but after that my EJBLocalHome and EJBLocalObject work as if they were cluster-aware EJBHome and replica-aware EJBObject.
Here is my code.
then started two nodes in JBoss with sticky OFF.
I do servlet->SessionFacade (Stateful Session Bean)->Local statefull session bean (my WorkAddressLocal)
My session facade has 2 instance variables, reference to EJBLocalHome and reference to EJBLocalObject. I initialize them when my Session Facade is called the first time. After that I store Session Facade bean in the session. Second requests comes around and gets load-balanced to the other node. Over there I successfully recover my Session Facade which has 2 references and test both of them:
//workAddressHome was created earlier in ejbCreate
WorkAddressLocal bean = workAddressHome.create();
//workAddressLocal was created earlier in ejbCreate
workAddressLocal.test();//success also !
Many thanks if anyone who can shed some light on the matter
