Was this while in the air? Were both spinning in the same direction?
When in gear, the other tire spins in the opposite direction per operation of the open diff b/c the trans offers resitance.
When in neutral, the trans does not offer the resitance to make the other wheel differentiate so the shaft (can) turns.
Sound normal UNLESS you have someone spinning both tires, same direction, while in gear, with no movement of the dshaft.
