With two large heaters only one would have to fail on to cook the tank which can happen faster than it cooling off and livestock tends to be sensitive to heat vs cold. Also two heaters means twice the chance of this failure mode. And yes external controller can help prevent it. Usually people set heater temp slightly higher than the external controller temp for added safety.
