I suppose if we were playing with toy soldiers on a game board, that would be the case. Did it occur to you that there was simply nothing worthwhile Gondor wanted further south? They got what they required in Umbar and Near Harad, and nothing more interested them. There is nothing to support what you are saying in the text.
