I think this form of Turing test could be passed by relatively crude AI that lack any form of human-level consciousness. Even smart humans can be deceived by clever programming that has been tailored towards answering questions that are likely to be posed in a Turing test, especially if the input/output is text-based. After watching Ex Machina, I think the form of Turing test they use is more informative. If you are shown that the intelligence is artificial, but cannot help but see the AI as human then the AI must be sufficiently good in order to overcome our initial preconceptions. However, this still doesn't necessarily distinguish between consciousness and simulated consciousness.
In reality, I think we will need multiple tests to uncover whether an AI is conscious, one of which may be a form of the Turing test.
