Ha. It figures. I suppose it's another one of those things you picked up in jai ... er ... I mean while you were somewhere else for a while.
I think the real point here is that magnetic domains can have any number of orientations (north, south, up, down, east, west, and points in-between. I don't pretend to understand "quadrature" (indeed, at a guess I'd have said it was probably a sort of medical support back-brace thingie you have to wear after having too many babies at the same time) I can imagine that what the CGB is trying to say in words of two sylables or less, and suitable for small, rapidly slimming orange-furred apes of little brain, is that it's a bit like three-phase AC power. Only to do with magnetic orientations, not phase angles.
