It is simple. Thats just primitive physics for a waves of any kind.

-1.0 inverts the signal, 1.0 just copy it. Sum of both cancel the signal to zero, we know it because we assumed the signal inverts itself. But our signals are sourced on different input channels and may have no correlation with each other. Yes it may but it may not. So it does not matter which one was inverted and which one is not, they just random signals and will give 2.0 in sum as a maximum. They may cancel each other but they may resonate as well.
