My mac's tar manpage doesn't mention no-same-permissions, but it does
say for -x:
"...file permissions are restored, if possible"
And has an option --same-permissions, which seems lonely and odd (but
this is a mac so it's either "BSD odd" or "value-added mac odd".)
The important note is that it *does* apply the umask to the extraction
by default for a normal user and preserves permissions by default for
the root user.
And while undocumented (in the manpage, but documented in the --help
output!), it does honor --no-same-permissions.
So, the bsd manpage on my mac doesn't document --no-same-permissions,
but it says that this tar is the gnu implementation (and that this is
the netbsd 1.0 manpage.)
