Actually what you say is true for LAN interfaces but not for serial
interfaces. The IOS will allow serial interfaces to be configured
within the same subnet as the following example shows:

Router_D#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int serial1/0
R1(config-if)#ip address 192.168.1.1 255.255.255.240
R1(config-if)#int serial1/1
R1(config-if)#ip address 192.168.1.2 255.255.255.240
R1(config-if)#

Clearly we have two interfaces in the same subnet and no error from IOS.
I would certainly agree that this is not done often. But it is a
possibility for serial interfaces.
