I believe that computationalism is by far the best foundational explanation of higher cognitive phenomena, as all other explanations involve some unscientific form of mysticism at one point or another. From this perspective, the answer to the question in the paper's headline is trivially true. Computationalism implies multiple realizability. It's worth noting that computationalism is independent from physicalism and monist materialism in general. It's not surprising that it's always paired with physicalism, but IMHO it's also the best foundational explanation for dualists.
