I need some help

I am struggling with the directions for the left back. How do I read the pattern at the instruction about the neckline, waist, and armhole shaping being worked at the same time?

My blog is a mess right now, I think it's a sign that I am done w/blogging. But I will post my progress here, when I get to that point.

I was so happy to find this KAL last weekend when I was struggling with "work in pattern as set." It all sounded so simple. But that is always my clue that I am not reading the pattern right. I have all of that figured out now, thanks to some of the pictures posted.

Thanks!
