When people point out there is no traction on an unseated axle, then ask them to pick it up.
Since the axle is articulating, one side is forced up, other side is forced down. Gravity has some effect, but not as much compared to that of the torque arm.
Biggest thing, at full compression, you are not compressing to the top of the shock body hits mount. At full extension, you are not hanging by the brake line (even when turned where caliper is away from frame) and the coil hasn't dislodged itself. Do note, even if coil comes completely off the upper mount/stub, if you wheel in debri, the debri may push the coil in such a way where it won't align back into position. That's the time you want to limit the down travel to keep coil in alignment.
