The axis is not on the center of the handle, it's closer to the massive end. Or, think of the design/shape of the Aerobe Epic. It does not spin on center axis until it flattens out.
EVERY THROW has a brief moment of horizontal axis OAT because we hold the disc with one hand.
Probably not the best term, but neither is snap, and that will never go away.
A different axis would be if you flipped the disc like a coin into a wishing well. You may be thinking off-center axis, but the disc won't fly that way...unless it's an Epic.
