That's an old wives tale.the high exhaust is so if the vehicle has to stop while fording a waterway it can still restart the engine. If you don't do that, the exhaust will flood with water when the engine stops, and during starting water will be pulled into the cylinder and damage the engine.
The exhaust valve is only open when the piston is on the upstroke, pushing exhaust gases out.
Also, the engine creates enough pressure to easily evacuate water from the exhaust pipe.
