FMS Multipoint publishing drops streams when adding a second server

So, we make a remoting call to choose which server to republish to and the onResult of the remoting call sends the data to this function to start the multipoint publish:

application.startMultiPoint = function(newURL, stream) {
     newURL += '2/'+application.theBroadcaster.userInfo.site+"."+application.theBroadcaster.userInfo.handle;
     
     var newUserInfo = application.theBroadcaster.userInfo;
     newUserInfo.multipoint = true;
     trace("CONNECT "+newURL+','+newUserInfo+', 1');
     nc = new NetConnection();
     nc.onStatus = function(info) {
          if (info.code != "NetConnection.Connect.Success") {
               trace("WTF CONNECT FAILED: "+info.code+": "+info.description);
          } else {
               ns = new NetStream(nc);
               ns.attach(stream);
               ns.publish(stream.name, "live");
     
               
               trace("PUBLISH "+stream.name+" TO "+newURL);
     
               var responseObj = new Object();
               responseObj.onResult = function(result) {
                    if (result.status == "OK") {
                         trace("*** Stream copied to "+newURL);
                         application.multipoints.push(nc);
                    } else {
                         trace("*** MULTIPOINT PUBLISH FAILED TO "+newURL);
                         nc.close();
                    }
               };
     
               var remote = application.remoteService();
              remote.multipoint_started(responseObj,
                    application.theBroadcaster.userInfo.site,
                    application.theBroadcaster.userInfo.pwsid,
                    newURL,
                    stream.name
               );
          }
     };
     nc.connect(newURL,newUserInfo, 1);

}
