Because most TNC's cannot operate at one speed on
RX and a different simultaneouse speed on TX.
Thus to serve the typical user, if he RX's at 9600 you have
to give him an input at 9600.

Of course, if he wants he can send at 1200.  There are
8 inputs for that..  But why require 2 TNC's per user
when one will do...

That is exactly the whole concept!  But then you have
to provide a 9600 baud input for those users that
are using 9600 baud to receive so that they dont
have to run two TNC's..
