Sure there's a reason-so you can spend twice as much money on interconnect cables!!!!
But seriously, the only reason for running your video cables through the receiver is to simplify video switching. If you don't have an issue with choosing the input on your TV when you change video sources, then there is absolutely no reason to spend extra money for the interconnects needed to use the receiver as a video switch.
BTW, I use the programable function of my HT remote to perform the TV input switching for me. Works great!
Enjoy,
