SO_REUSEADDR just make sense for server?

Question

I am working with two binaries which use UDP sockets. Process A waits for messages on a UDP socket (IP_1:PORT_1) by select(), and process B eventually sends through an UDP socket.

By some constraints out of scope, process B needs to send by a socket on (IP_1:PORT_1). Since this is the same IP:PORT pair for both processes, it is not possible to use bind(). I tried SO_REUSEADDR, but I am wondering if reusing the IP:PORT with SO_REUSEADDR for sending and receiving makes sense, or was this option conceived just for listening sockets?

process A

int nOptVal = 1;
setsockopt(UDPSocket, SOL_SOCKET, SO_REUSEADDR, &nOptVal, sizeof(nOptVal));
bind(UDPSocket, (struct sockaddr *)&addrLocal, sizeof(addrLocal));

select(fdMax+1, UDPSocket, NULL, NULL, NULL);

process B

int nOptVal = 1;
setsockopt(UDPSocket, SOL_SOCKET, SO_REUSEADDR, &nOptVal, sizeof(nOptVal));
bind(UDPSocket, (struct sockaddr *)&addrLocal, sizeof(addrLocal));

sendto(UDPSocket, buff, len, 0, (struct sockaddr *)&addrDest, sizeof(struct sockaddr));
