Patons Pirouette Ruffle Scarf Question - Every Second Space?

I've noticed the pattern for the Patons Pirouette Scarf says to knit in every second space, but the pictures look like they are knitting in every space. They may have a different definition of "every second space" than I do. The spaces are staggered, and you only knit into the top row of spaces. Are they counting the staggered spaces on the row below as the space between spaces?
