The photospheric flow caused by the reflection effect in an early-type star, which is a nonsynchronously rotating component of a close binary is calculated. These large-scale, unsteady currents result from the presence of a moving 'hotspot' that is sweeping the star's equatorial belt. It is shown that they are confined to a thin thermoviscous boundary layer. Because the radial component of the circulation velocity is very small, it is also concluded that the reflection effect is not likely to hinder systematically the gravitational sorting of the chemical elements in the external layers of a slowly rotating, tidally distorted A-type star. In nonsynchronous rotators with very short orbital periods, however, diffusion might have a marked preference away from the equatorial belt, where the vertical speed in the moving 'hotspot' attains its largest value. According to the semiquantitative calculations, this upper limit is still less than a few cm/s in a 4-day period A-type star.
