I would check the Windham Fabrics website for any pattern corrections. I suspect there is a typo there.
Here's how I understand the directions. You make strip sets. Then you cut the stripsets into the diamonds for each star point. One of your quilting rulers should have a 60 degree line on it. Don't overthink this. It is not rocket science.
I really think the reference to 45 degree angles and squares is a misprint. Just look at the picture.
