These directions are incorrect, in absolute terms.
If, at the eastern horizon, the star drifts south, then the mount is moving north too much, meaning that the axis is pointing too high, and needs to be moved down(I need a diagram here).
At the meridian, if the star drifts south, then the mount is again moving too far north, meaning that the axis is too far west, and needs to be moved east.
Have a good look at your mount in the daylight and check that moving the knobs works as you expect. I spent a good few hours in the dark with an erroneous idea of how my mount worked, trying to figure out why I could not get it aligned. Also take account of any optical 'flips' in your light path.
I also found that writing down a set of instructions for myself and testing these under the night sky kept things clearer in my bamboozled mind.
