There aren't any intermediate states, so there is a loss of precision as the entire movement is linearized per batch of updates (single target position). The important difference is that the velocity and error stuff doesn't get aggregated across the batch of user commands so the player doesn't suddenly teleport or move faster.
And yes, the underlying functions still work, but the controller will of course modify the velocity of the object.
