why does freebsd-update and uname report different patch levels?

[James B. Byrne]

We have recently completed upgrading all of our freebsd-11 systems to
11.1.  Now when we run freebsd-update fetch we see this:

# freebsd-update fetch
src component not installed, skipped
Looking up update.FreeBSD.org mirrors... 3 mirrors found.
Fetching metadata signature for 11.1-RELEASE from
update5.freebsd.org... done.
Fetching metadata index... done.
Fetching 2 metadata patches.. done.
Applying metadata patches... done.
Fetching 2 metadata files... done.
Inspecting system... done.
Preparing to download files... done.

No updates needed to update system to 11.1-RELEASE-p3.

However, when we do 'uname -a' on the same system then we see this:

FreeBSD inet13.hamilton.harte-lyne.ca 11.1-RELEASE-p1 FreeBSD
11.1-RELEASE-p1 #0: Wed Aug  9 11:55:48 UTC 2017    
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

Why is there a difference in the reported patch level of the same system?
