Why Voynichese doesn't have cribs?

2) Polyalphabetic cipher on the other hand may use the same amount of symbols or fewer than the alphabet but symbols have different meaning depending on their context. It is actually "many to many" cipher and not "one to many". An example would be Vigenere cipher: You are not allowed to view links. Register or Login to view.

I'm not sure I use the proper terminology, but for me "many to many" implies that you cannot reconstruct a unique plaintext, there will always be uncertainty. And "one to many" for me means many possible ciphertexts encoding the same plaintext, but only one possible plaintext corresponding to a ciphertext.
