90% of the lecture time is spent saying 'I'll create this node and connect it here.' The part where the instructor explains the intent during the creation process is extremely minimal, so it's essentially no different from just looking at a collection of examples. The lecture doesn't cover how to approach creating results. For node explanations, if they had been prepared more properly, there should have been materials like a graph showing value changes over time for Time Sine, or a graph showing linear mapping between input and output for Remap.
