As has been pointed out elsewhere, even if one of the pilots did deliberately move the switches, it's not clear from the reporting so far if that's the same pilot who responded to the question. In other words, it's possible one pilot flipped the switches and then asked the other pilot why he cut off the fuel to misdirect and create more confusion.

Edit: Of course this is all speculation, we don't know if the switches were moved deliberately and if so which pilot did so and which pilot was which in the exchange. More investigation is clearly needed.
