A simple question about patches for FreeBSD from http://security.freebsd.org/patches

Dear sir, My first language is not English, please forgive me if I made some bad words. And I do not know if that is the right e-mail address to ask questions. I copy a few lines from http://security.freebsd.org/ - FreeBSD-SA-07:05.libarchive.asc

Re: A simple question about patches for FreeBSD from http://security.freebsd.org/patches

Is that mean if I use 5.5-release, I should apply all the patches above and if I use 6.2-release I need only apply the FreeBSD-SA-07:05.libarchive.asc to FreeBSD-SA-07:02.bind.asc
