Separate conductors for separate frequency ranges in cables

On this issue, I'm both skeptical and open minded. I'm approaching this in a good faith manner. I saw an ad on Agon for PS Audio power cables and the description reads, "Inside the AC12 are three hollow PCOCC conductors for the treble regions, one massive PCOCC rectangular conductor for the midrange and multiple gauges of PCOCC bundled together for the bass." I read that and just thought to myself, what does PS Audio mean? There is no crossover within the cable that literally separates frequencies and delivers them to separate inputs of a component. I can understand how different types of conductor materials/geometries can optimize different frequencies, but I don’t see how this would work in a single cable. Not too dissimilar are “Shotgun biwire” or “single biwire” speaker cables, but at least in that application you end up with two separate connections at the speaker – one to the bass woofer, and the other to tweeter and midwoofer. Is there anyone out there that can more fully explain what PS Audio is trying to accomplish with this cable construction? Honestly, I’m just seeking to understand, not cast aspersions. I really dig a lot of what PSA does.
