Yep, I am doing a coriolis sock from the book now and it is VERY different and quite cool. I have made about 8 pairs of socks and so I have an idea about how socks are made, both cuff-down and toe-up. These are clearly different.
In fact, I never had such trouble knitting a sock!! I guess I am not as good at taking accurate measurements of my foot and my gauge as I thought I was! I never had to rip a sock back before. I have ripped this one 4 times....so far. But, I still want to keep going. I feel like, if I can "get" this, it will be a real insight.
