Actually the only point I was making was about the use of the word "phase" in place of the word "polarity".
Phase infers time among other things. The word "phase" is misused a lot.
Here's an article by Bob McCarthy
PHASE AND POLARITY
Before we move to the next section, time for a pop quiz. How many milliseconds of delay results from 180° of phase shift?
Is that your final answer?
The correct answer is, “That's a trick question.” Why? Because a frequency must be specified. So how many milliseconds of delay are equivalent to 180° of phase shift at 250 Hz? The answer is 2 ms.
Now, how much time delay do we get when we put a phase reverser in-line? It reverses all frequencies by 180°, so it must delay each one by a slightly different amount. That is quite a fancy delay circuit there! And I thought it was just swapping two wires!
In reality, there is no such thing as a “phase reverser.” It is a polarity reverser.
Polarity reversers do not delay the signal. They invert the voltage or pressure component of the signal. While this does shift the phase, it does not change the phase delay time. That is not to say that a polarity reverse is unimportant. Anything that affects the phase will dramatically affect the way that different signals combine."
