No.

The Earth's rotation projected into space in terms of geostationary satellites which reflect longitudinal fixed position albeit at a greater height and a faster rotational speed is only one of two distinct rotations.

The satellite has a forward motion through space as the Earth has so it will register the orbital surface rotations just as ringed planets display a surface rotation parallel to the orbital plane aside from and addition to daily rotation. The 4 degree orbital surface rotation of Uranus and its rings provide the observational certainty (about 50 seconds in) -

A satellite in an orbit circling the circle of illumination will see the North and South poles turn beneath that satellite as a reflection of both the forward motion of the Earth through space and the slow and uneven rotation of the surface parallel to the orbital plane -

The Equation of Time reflects the same combination of surface rotations, one rotation asserted to be constant (daily rotation) and the other uneven (orbital surface rotation.

This is not a competition, if people want to follow the principles then so be it or they can call out from the shadows about imaginary perturbations.
