Yarnovers on the Purl side

Wanting to show this as clearly as I can, thus the large needles. I purl a stitch and then go into the yarn over. With the working yarn in the front I go over the top of the right needle once and bring the working yarn back into position to purl off the two next stitches.. the decrease part of the yarn over. If I wrapped twice, all that would happen in my case would be a giganic loopy yarn over.
