[Elecraft] K3 RX only in port - still confused?

[Robert Dorchuck W6VY]

Now I'm confused.  From the FAQ's:
----
If the transverter option is not installed, can the K3 use ANT2 as a de
facto RX ANT?

Yes.  If the KXV3 is not installed, you can designate either antenna to
either receiver.
----
I can't see why I would have to order the transverter option
(which I have no use for) to use two antennas.
