No, we don't mean the same 88. There are two 88's in the pass/between the cliffs, one at the El Dhib flag ("first flag") and one in the mainbase (useless really since you are not allowed to attack main), for a total of four.
That said, the gap between Kidney and Miteriya ridges is and always has been the weak point. The 50mm guns on Kidney can't oneshot Crusaders and have trouble killing Shermans at all, so adding one "invulnerable" tank into the mix hardly matters. Climbing the Miteriya along the "spine" will be rather challenging with the Churchill, so it will trundle along two predictable routes, one of which has two 88's (the pass) and one of which can be blocked with Stukas and F2's/Marders (the Kidney gap).
