() ->{a->{a, b}, b->{a}} $$() ->{a->{a, b}, b->{a}}$$
Since the words were encrypted with the same key, that means if we were to generate a possible key, that key would need to decrypt both ciphertexts such that when the tree is navigated we navigate to nodes that exist. If the key results in a path in the tree that does not exist, then we can disregard that answer as a possible key and continue with the possible next key.

Once you find a key that is the same length as the cipher text, we know that we found the right key. Once you find a key that is the same length as the cipher text, we know that we found the right key.
