Evidently redundancy is not easy to specify but the hole in the north wall shows that you can remove a fair amount of wall columns and nothing happens (except that adjacent columns in the north wall become higher stressed but still have ability to carry the total load in the wall above).
The alleged deflections in the south wall cannot develop as the stresses there are virtually unchanged with the hole in the opposite wall. I have a distinct feeling that the pictures shown above are faked and it can probably be verified by checking other forensic evidence, history of which is known.
