Because the IP's you add in the Server NAT tab are then made available
in the Inbound NAT rules drop down box.  You could do it all in the
Inbound NAT tab by replacing the drop down box with a text box, but
I'd say that greatly increases your chances of mistakes there.  There
also might be a reason on the back end that it's done that way.
