Need help interpreting "K2 Sl2wyib" eek, how does that work?

My pattern calls for this to create stripe pattern. The next row calls for “K2 Sl2wyif”. Can’t find how to do this.

K2 sts, bring the yarn to the front as if you were going to purl, slip 2 sts, move the yarn to the back to knit the next sts if that’s what they are.

There’s a video here for the Slwyib. You’ll actually knit 2 and then slip 2 but it gives you the idea for the slipped sts.
