Well, it will return true if you _have_ CAP_SYS_ADMIN capability. Typically root has all effective capabilities (except CAP_SETPCAP). You can check your effective capabilities in /proc/[pid]/status. I doubt your system can't get a process with CAP_SYS_ADMIN, you'd have trouble mounting filesystems, etc...
