Knitting a YO

I watched the yo video and I understand that. But does it give you an extra stitch everytime you do it? What do you do when you come to that yo on the next row? My pattern has a row with yo’s then the next row your are back to ribbing. You start with 48 stitches and then after the ribbing you are supposed to increse 1 at each end to 50 sts. What happened to teh yo’s? this is the beading section I am talking about.

This is the pattern.
