According to /usr/src/Makefile's comment header, the
step "make delete-old" is followed by a reboot (in
combination with the 2nd mergemaster run, after
"make installworld"), while "make delete-old-libs"
is performed after the reboot, without a further one.

In /usr/src/Makefile, you can find the following order:

# For individuals wanting to upgrade their sources (even if only a
# delta of a few days):
#
#  1.  `cd /usr/src'       (or to the directory containing your source tree).
#  2.  `make buildworld'
#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
#       [steps 3. & 4. can be combined by using the "kernel" target]
#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
#  6.  `mergemaster -p'
#  7.  `make installworld'
#  8.  `mergemaster'            (you may wish to use -i, along with -U or -F).
#  9.  `make delete-old'
# 10.  `reboot'
# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)

Additional information from "man 7 build":

     delete-old	      Delete obsolete base system files	and directories	inter-
		      actively.	 When -DBATCH_DELETE_OLD_FILES is specified at
		      the command line,	the delete operation will be non-in-
		      teractive.  The variables	DESTDIR, TARGET_ARCH and
		      TARGET should be set as with "make installworld".

     delete-old-libs  Delete obsolete base system libraries interactively.
		      This target should only be used if no third party	soft-
		      ware uses	these libraries.  When
		      -DBATCH_DELETE_OLD_FILES is specified at the command
		      line, the	delete operation will be non-interactive.  The
		      variables	DESTDIR, TARGET_ARCH and TARGET	should be set
		      as with "make installworld".

To conclude this into an answer that matches existing
documentation:

Yes, "make delete-old" requires a reboot. :-)
