Switch System

But I guess the point is that in my opinion the text was cornered in this example, and much of it is to one degree or another cornered.

The why of it I guess is the interesting part, and on that I have no clue.

If the text is a one-to-many cipher (there are several ways of encoding the same plaintext) and a certain ciphertext sequence can have several plaintext interpretations depending on context, sometimes it could be necessary to break the normal flow to avoid ambiguity. It's similar to how natural languages sometimes use diacritics to break diphthongs, like naïve or coöperate.
