With this thought, I realized my interface name was not same as my mac address since I set the mac address from userspace. I thought this is a bug but I also see your point of view which is NamePolicy=mac means hardware's mac address as also stated in the man page.

By the way, I'd be happy to take suggestions on how the man page could
be made clearer.
