I don't know where you read that, but I wouldn't put much faith in it.

Unix-domain client sockets are normally unnamed; there is usually no
reason for the client end to have a name.

Unlike TCP/IP sockets, where each end always has a port number, and an
ephemeral port is allocated by the OS if none is chosen explicitly,
Unix-domain sockets don't have to be named. E.g. with socketpair(), both
sockets are unnamed; as they are connected from the outset, there is no
need for names.
