FreeBSD security advisory message will tell your if reboot should be 
last step of particular update.

If you want to use your own brain, think along these lines: if anything 
inside kernel has changed, you do have to reboot (as you have to replace 
something that is always in RAM when system runs); if nothing has 
changed that is loaded into RAM with the kernel, then no reboot is 
necessary. An example of the last would be update to one of the binaries 
(utilities) that comes with the base system (not to be confused with 
stuff coming with pkg or port installation).

I hope, this helps.
