Delaying the Tawaf of Ifadah until departure suffices in place of the Farewell Tawaf

If one delays the Tawaf of Ifadah and performs it upon departure, does it suffice for him in place of the Farewell Tawaf?
Yes.
However, it may be difficult for some people to understand how this is valid, given that he will perform Sa'y afterwards if he is performing Tamattu', Ifrad, or Qiran, and he did not perform Sa'y with the Tawaf of Arrival.And the answer: Sa'y is an accessory to Tawaf, so it is not considered a separator; because it is an accessory to Tawaf, it does not contradict the fact that his last act with the House is Tawaf.
