That explains it.  Using one connector, the card terminates one end
of the SCSI cable.  Using any two of the connectors, the card is
in the "middle" of the SCSI bus.  But if you were to try to use
all three connectors, then you *would* have a "Y" cable situation,
which I'm sure would lead to all sorts of nasty reflections on
the bus (in certain/most cases at least).
