Facing the patchwork pocket- Help?

I don't yet understand how to position the facing in order to follow the directions for attaching the facing to the patchwork pocket. How do I sew the initial 1/2" seam allowance, then pivot at the corners while not completely sewing the edges of the facing to the pocket. The image shows a 1/2 SA all along both the pocket and facing, with the facing still free along its edges (it's flipped up/away from the actual pocket). I've attached pics of the directions and of the 2 options the directions may be conveying in order to attach these pieces, with right sides together. Can you say whether the pinned example or the non-pinned is the way I should start? Maybe it's something else?🤷🏻‍♀️ Thank you!
