My by-pass goes from the intake to the heater core and back to the pump. I always assumed it was like that to get the temp. up quicker for the heater in cold weather and help with warming up the engine before the thermostat opened. All cooling systems are not the same though. Old trick for racing street/strip car's in hot weather was running the heater blower to help cool the coolant circulating.
