You would be if you would use the correct terms which are
NOT SO CONFUSING. There is a good reason for getting
the terms right, beyond just being picky or pedantic.

Both servers should use:
Preferred: Itself
Alternate: It's partner (nearest partner if more than one available)

Clients should use either as Preferred and Alternate.
Preferably having half the clients use each as Preferred
and the other as Alternat IF there are a large number of
clients and some easy way to do that.

If there is a distinction the clients should use the "closest" as
Preferred.
