Until recently, the patents listed for each product were the most pertinent/reality-based technical info Dimarzio was willing to share about their many distinct and proprietary flavors of vanilla. The product descriptions are mere ads, ranging from boilerplate to nonsensical (“Thundering cloud of ice cream”, anyone?); and should be taken with a grain of salt.
The description seems to reference their “dual resonance” patent, which consists of winding a humbucker’s two coils to different resistance measurements (e.g. an 8k humbucker with coils measuring 3.9k and 4.1k). Dimarzio achieves this in a few different ways, depending on the design. Essentially, the intended result is for the phase cancellation between two different coils wired in series to produce a pickup timbre that seems to emphasize whichever particular frequencies aren’t being cancelled out.
Steve Blucher has been experimenting with this for at least thirty years; so Gilbert likely submitted an abstract request that the neck pickup of the set sound like refried beans or something. Steve likely felt that the prototype Paul approved sounded more like a single coil than humbucker, and that impression subsequently made it into the ad copy.
Concerning coils: Dimarzio pickups have, at most, two coils/bobbins. I recall some goofy three-coil humbuckers from 20 years ago, but that’s it. Every Dimarzio humbucker (with the partial exception of the Bluesbucker) is “intended” to be mounted with the screw coil facing “out”, but you’re free to flip them around if you feel they sound better.
