As well as marking flows this indirectly marks the ipv4 routing cache as every routing entry contains a flow. It is useful to add the network namespace into flows as frequently the routing information for ingoing and outgoing network packets is collected into a flow structure which is then used for several functions as it sorts out what is going on.
