HDS-3/HS-23 3.5mm Mod Question

Few questions regarding the 3.5mm mod for nokia headsets.
1. From my own observations the HDS-3 and HS-23 dont use a common ground for each earphone. How then does the hadphone jack mod (all 3.5mm jacks use a common ground) work in full stereo. Is this where the seperation issue between channels comes into play.
2. If the AD-15 does have full stereo does it have some kind of extra circuity inside to allow the use of a common ground?
3. Does anyone have an pics of the internals of an AD-15 headset?

Thanks doc
