It's possible that you're getting confused with the different UUIDs
that are used. diskutil lists the “volume” UUID which is different
from the UUIDs that are used in the GUID partition scheme. The volume
UUID for HFS+ filesystems is stored within the filesystem, not as part
of the partition table.
Kind regards,
Chris
