My claim is that given a list of binary sequences I can find a
sequence
not on the list.
To support this claim I need only one diagonal. When you gave me
two diagonals I chose one and supported the claim.
Your claim that you can get a generalized diagonal with any finite
prefix is true, but irrelevant. You cannot set the generalized
diagonal to an arbitrary sequence.
