No, I think it's only a double yo - yfd just brings the yarn to the front, yrn wraps it around the needle, then yon would be another yo.
The stitch count works out that way - k3 yo2, k2tog, yo2, k2 tog, k1 and you'll end up with 10 loops on the needle.
"K3, yfwd, yrn, yon, k2tog, yfwd, yrn, yon, k2tog, k1. (10 sts)"
