The temperature of the drywall is above the dewpoint of the warm air on the warm side.  However, on the cold side of the drywall, and to some extent in the thickness of the drywall, the temperature is below the dewpoint of the warm air.   So condensation should ocurr in those colder regions of the drywall as vapor diffuses into those regions.

But, as I've shown, the rate of diffusion of the water vapor is such that condensation will not occur.
