Here I tryied to show what I mean (Hope the imgur link works)
There is chance that I didn't understand your path/curve the way you intended. Yet it looks to me that on the first page you accidentally jumped from one area of curve to another. I tried to convey the way I see your paths in 3d space with different weight of red line.
Hope that makes it clearer. If not - ask again.
Don't worry about organic perspective exercise though. It is mainly just an introduction to a spacial problem that we will have to solve much later.
You're welcome!
