You would only ever have one wheel getting power if there were open diffs and an open TC. It's obviously not 100% locked up, and can obviously slip a a bit. Think of it like an LSD with 99% lockup. Definitely not open.
Right, the center diff is a locked (kinda) diff. The speed variation is done left to right not front to back. So the front and rear diffs account for the variation in wheel speed.
