What _is_ the difference?

In the system log (displayed by dmesg), the kernel version will
be logged as issued by the kernel itself. If the kernel was not
subject to freebsd-update, its version number won't change - so
you have the "old" kernel version and the "new" world version.

After freebsd-update, the system will run the patched version,
of course.

The MOTD (/etc/motd) is a text file which you can manually modify.
The placeholder for the version information uses the version
obtained from the kernel, according to "man 5 motd". Check the
setting "update_motd" in /etc/rc.conf (/etc/defaults/rc.conf)
as well, and see /etc/rc.d/motd for details.
