I think you would probably need to do both because the DEC drift due to altitude is more pronounced when you are pointing near the horizon and due to azimuth when you are near the meridian - hence the way drift aligning works.

You would need to ensure you make the adjustment to each axis consistently so it doesn't swap from a north drift to a south drift as you track from horizon to meridian as this would cause the guider to change the direction of the DEC corrections.
