Twisted pairs will have higher capacitance than non-twisted pairs in Cat5. The medium between non-twisted conductors is mixed - air and dielectric - but will always be greater than the twisted pairs.
So, comparing a twisted DQ/GND and DQ/GND combination to a DQ/DQ and GND/GND twisted pair set, the former will of course have more capacitance per unit length. To be more accurate, I could have said "reduces capacitance problem", but what I meant was 'in comparison to standard multiconductor cable'.
