I'm afraid my comment above was wrong. Greenmonkey had it right, it would seem to be a fairly intelligent cable design based on the limitations.
Yeah. I hate proprietary cables myself. But at least this way, you can charge with standard micro-b USB in a pinch or if you lose your cable.

It must have something to do with charging speed. Because I think you can push more than the .5 amps through a standard USB cable (look at double-ended USB cables for portable HDDs....2 .5a usb cables -> one micro usb for a total of 1a), but maybe the extra pins are to help deliver that extra amperage effectively to the Nook battery.
