On: Convolution Is Fancy Multiplication

[convolvatron]

imagine you are able to see the wave as it hits a wall and reflects. the reverse signal is 180 degrees out of phase with respect to the forward.

[rualca → convolvatron]

You should be more careful and precise in your attempts to describe these things. Inverting the phase of a signal is entirely different than inverting the signal. Time-reversed signals are not the same as phase-reversed signals.
