DUH...I'm completely wrong.  What is reduced is crosstalk
between pairs.  Brain cramp. Sri.  EA

Tom's right.  What you were thinking of is telco cable, 
where the pairs are twisted for a distance, then twisted 
in the REVERSE direction for an equal distance.  the result
is that at audio frequencies, the net capacitance is reduced.

Twisting always increases capacitance between pairs. Haven't 
you ever used a gimmick capacitor??  :-)
