remoting-ejb-receiver to the server itself

Two ears- one.ear and two.ear are deployed on same server group. server group contains multiple server hosted on different hosts.
* one.ear makes a remote ejb call in two.ear
* two.ear makes a remote ejb call in one.ear

do we need to define outbound-socket-binding/remote-destination to the server itself.

for example. 4447 is remoting port for all servers the server-group

    
    ...
      
        
      
      
        
      
    ...
    

where

my.host1.com

my.host2.com

also in full-ha profile, here my.host1.com has one outbound connection to itself on port 4447 and other to my.host2.com

do we need to create an outbound connection to server itself ?
is local-destination-outbound-socket-binding something we should using in this case ?

Thanks
