The first 3D sketch is the path and the second 3D sketch is used as a guide curve. Notice the difference in the model if you skip the guide curve.

In earlier versions of SolidWorks it was necessary to have separate sketches.
In this demo, 1st tutor is opt for one sketch then he changed his mind and going to two sketches. That is what cause for concern.
