Correct.

Also correct, *but* it does help if you want to install something from
stable that has been removed from testing.

In the absence of "pinning", using the two lines that The Wanderer
posted would give you a testing system, with the option to pull in
packages from stable if needed.  It's a viable setup.  Sensible.

The problem is, sometimes people think it's the opposite of that.
They think they can run a "mostly stable" system with the option to
cherry-pick packages from testing.  This is *NOT* the case.  And no
amount of "pinning" will make it so.

(If you actually want such a system, use stable-backports.  That's
what they're for.  Do not pull binary packages from testing.  I know,
we say this every 3 days, but that's because the issue *comes up*
every 3 days.  We can't stamp it out.)
