synth upgrade-system is restricted to the installed ports.  That's what
it does.  It gets it build list from pkg(8).

Synth is a local respository builder, that's it's purpose.
In a nutshell, you get your local respository up to date, and then
pkg(8) updates everything using that repository.  If you didn't update
the repository, then pkg(8) doesn't know the package has been built (in
theory you can use manual pkg(8) commands (e.g. pkg add) to update the
system without having to rebuilds the repository.

If you have 5 ports that you want to manually/individually update, then
you'd use something like "synth install port1 port2 port3 port4 port5".
 That will rebuild everything necessary (incremental), then rebuild the
repository, then install everything.  You wouldn't do 5 individually
build/install commands.

more clear?
