According to the handbook [1], freebsd-update does indeed merge 
configuration files:

Confusingly the handbook explicitly says that mergemaster is not used 
but refers to mergemaster documentation for more info.

The file merge process is a series of diff(1) patches similar to 
mergemaster(8), but with fewer options. Merges are either accepted, open 
an editor, or cause freebsd-update to abort. When in doubt, backup /etc 
and just accept the merges. See Section 23.6.4, “Merging Configuration 
Files” for more information about mergemaster.
