So what in your head measures 180 ?

you have no idea, humans ears can detect amplidue/volume NOT phase.
if you add two signals that are in phase the sound beomes louder.

That is what you're ears are detecting the resultant amplitude and that is it.

I suggest you read the rest of that article you pointed us at the other
day. This one:

Yes I have done thanks .
The human ear is insensitive to this kind of phase change of delay, as long as the delay is constant and we dont have another signal to reference it to.

Good.

Now the point about a stereo audio system is that it has two speakers
playing closely referenced audio.

Which is exactly what the human ear can detect.
