In that case, Linux will "rotate" between them, using one or the other for each outgoing packet. If you want all your outgoing traffic to go through one gateway only (from what you write, that is probably what you want), only remove the GATEWAY= line from the :0 and :1 files and restart the network with "service network restart".
