    Nah, they are using the wrong definitions;

    > where work is extracted from entropic resources, such as system-bath correlations

    When the "bath" is correlated with the "system", then the "bath" is part of the "system", not an external "bath".

    You can do the same trick with a classic system If you have a magical "bath" that has just the right positions and speeds to give the piston a big push at the right moment, you can extract work from the "bath".
