Godel's proof you are quoting from had NOTHING to do with undecidability,

On questions whether Gödel said something or not the sumpreme authority
is not Mendelson but Gödel.
When some authors affirm that undecidability and incompleteness
are the exact same thing then whenever Gödel uses the term
incompleteness then he is also referring to the term undecidability.
That does not follow. Besides, a reference to the term "undecidability"
is not a reference to the concept 'undecidability'.
