No, freebsd-update should update your /etc/profile and UNAME_* system vars.

If there's no UNAME_* defined, you undefined it with #unsetenv, uname reads them from /usr/obj/usr/src/sys/$KERNEL/vers{ion,.c} files. Trond suggest to delete them before rebuilding, so they get updated too, nice suggestion. Mine sets different information in UNAME_* and vers{ion,.c} files. This discrepancy should be avoided.
