وَيَجْعَلُ طَوَافَهُ مِنْ وَرَاءِ الْحَطِيمِ.
Translation: He performs his tawaf around the outside of the Hatim.
Here the Hatim means the semicircular Hijr Ismail enclosure. The route of tawaf passes outside that enclosure to circle the full sacred structure.
Cutting through the enclosure does not produce the required full circuit. Correcting an actual interrupted round requires attention to its specifics.
