I tested it for a couple rows and I think I figured it out!
On the pattern rows, the odd numbered ones, you slip pwise with yarn in back. On even rows (alternate rows) you slip pwise with yarn in front. The reason you do this is because the even rows are technically the back or WS. If it helps you can put a safety pin or locking marker on one side to remind you. Give it a try and see if that works for you.
