Unusual using for LM317/LM337 in a PS for Power Amp

Symmetrical high current power supply using LM317 and LM337 in an unusual configuration - circuit description wanted

Except in the Linn LK2/LK280 I haven't see such a circuit - go to post #51 under
http://www.diyaudio.com/forums/solid-state/106226-tweaking-classic-linn-lk1-lk2-lk280-6.html (last pdf-file, see bottom).
An important feature is the fact, that any voltage drift take place on both rails at the same time.
How works this circuit in detail and what one can do better ?
What other amp manufactures uses also this topology?
Thank you for advices.
