I see, thanks. You're correct that it's a long course recorded and edited in big batches, then split up to make each part a bit easier to digest or navigate back to - rather than having a 45 min. tutorial here, a 20 min. one there.
I'll be more careful to help people to follow along in the future, between videos. It has a lot to do with the phrasing I think. I'll keep that in mind.
