Just to clarify, the lines on the map are exactly the same, there is no difference in how you mark the chart, well actually there is, if you turn the chart until the track line you drew is pointing in the direction you are flying, you might want to write any notes or numbers so that you can read them with the chart rotated on your knee to 'track up'.
It is not a different planning technique, it just refers to how you hold your chart in the aeroplane.
