I think there is an error in the statement of part (iv) of the exercise which probably stems from the replacement of $\pi z$ by $z$ in part (ii).
It seems to me that the exercise should read:
"By integrating along any path from $0$ to $z$ that avoids integer multiples of $\pi$,..."
This is because on the RHS of the result in part (iii) we want to avoid values of $z$ for which $(z^2-n^2\pi^2)=0$.
