Your answer is logical, but not true for Cisco. Cisco lets you do back-to-back Frame Relay. I think they added it mostly to allows training classes to save on equipment costs!
If a person can afford to use a router in the middle as a switch, it really enables a better understanding of Frame Relay. When you configure the switch especially, light bulbs often go off. The back-to-back stuff, on the other hand, muddies one's understanding. But it should work. Just make one the DCE, add clocking, and the frame-relay switching command.
