  They appear to be mutually exclusive.

execve("./test-socket", ["./test-socket"], [/* 24 vars */]) = 0
arch_prctl(ARCH_SET_FS, 0x602538) = 0
set_tid_address(0x602570) = 9828
socket(PF_LOCAL, SOCK_STREAM|SOCK_NONBLOCK, 0) = 3
setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
socket(PF_LOCAL, SOCK_DGRAM|SOCK_NONBLOCK, 0) = 4
setsockopt(4, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
unlink("/tmp/socket") = 0
bind(3, {sa_family=AF_LOCAL, sun_path="/tmp/socket"}, 110) = 0
bind(4, {sa_family=AF_LOCAL, sun_path="/tmp/socket"}, 110) = -1
