Full disclosure, I'm not 100% certain that air with water vapor has higher thermal conduction at low temperatures.
We're just talking terminology here, but it is definitely convection we're talking about here, not conduction, at least as the terms are commonly used. Conduction is the transfer of heat through solids; convection is from a object to a fluid, in this case from the solid surface of the water bottle to the air fluid.
