I don’t recall ever seeing that with space walks in shows before. But depending on the show, in many there’s typically some form of inertial dampener and/or artificial gravity generator tech (or the equivalent) in the canon that allows for the crew to remain more or less stationary/move around normal and attached to the ground even while accelerating/decelerating and in stable orbit. Given such tech is always kind of handwave-y because such tech isn’t actually feasible with our current understanding of physics, it could be argued that they are the cause of what you describe.

Like if the role of the inertial dampener is to keep your position absolutely stable relative to the ship absent forces acting on you, if the radius of its influence extends outside of the ship to some degree, you might expect them to slow and stop relative to the ship once their thrusters stop. And same with the artificial gravity, if it extends out of the ship some and “downward” is directed towards the ship, you would expect them to be able to walk on the hull and even “fall” towards it.
