Phase is just a measure of time relative to frequency. You can configure a multi-way loudspeaker to have a nice Phase response (Step response in a Stereophile Review) for s place is space relative to the driver. All other places the phase response differs... it's not in phase.
The brain uses timing variation between the ears with similar signals in the mid and low frequencies to assist in location. It is fairly precise tool for live sound, though it can be fooled as well. In stereo reproduction, however, the brain isn't sensing "Real" it is sensing "fake" and has to process what "might be real" and imagine it!
How the individual signals are recorded, and modified in the production process virtually never preserves phase (Binaural and a other specialized methods excluded). Nor the producer and engineer have to create the illusion of direction and do so using many techniques.
In the end, however, playback systems that preserve phase and those that don't can do a fine job of assisting us listeners in creating the illusion.
