Help, k1p1 in yarnover

I cant figure this out, does the result = 3 stitches. I knit into the previous row yarn over, without slipping it off my left needle, then pull the yarn to the front as if to pearl, taek my right needle back through the same yarn and do a full pearl stitch??? I really need a video to show my how this is supposed to create 1 extra stitch???

From what I can tell, k1 p1 in the yo would create 2 extra stitches, not one. The only thing I can think of is if you’re supposed to drop the yo somehow, but I think the pattern would tell you that somewhere. :thinking:
