You're right Francis, BSD manual of socket syscall says:
SO_REUSEPORT allows completely duplicate bindings by multiple processes
if they all set SO_REUSEPORT before binding the port. This option per-
mits multiple instances of a program to each receive UDP/IP multicast or
broadcast datagrams destined for the bound port.
