The architect Mark Lehner suggests that the corridor represented the untamed wild, surrounding a clearing – the open courtyard – of which the king was guarantor. From the reliefs depicting ships on the east-corridor west-wall and west-corridor (transverse corridor) east-wall, the Egyptologist Dorothea Arnold contends that the courtyard and corridor form an architectural unit analogous to the Egyptian "benben" myth. The other reliefs present symbolize the king's role as guarantor of order and prosperity on the sacred island. Among the reliefs of this room a significant discovery was made. One of the individuals present has been modified to include a brief inscription identifying them as "Neferirkare King of Upper and Lower Egypt" ("nsw-bit Nfr-jrj-k3-rˀ"). From this detail, Kurt Sethe, who was responsible for compiling and preparing the scenes for publication, developed the hypothesis that Neferirkare Kakai and Sahure were brothers, and that Neferirkare had had the relief corrected after ascending to the throne.
