17. z integral in eq. (13) passes through regions where δ ≈ 0 in eq. (11). i.e., the second-order perturbation is not justified. However, the main contribution to the integral certainly comes from the regions where we can use eq. (8). Notice that δ = -1/8 at the maximal orbit when the magnetization takes a local maximum.
