I know it's not a bind off, but it's LIKE one in that's what they mean be pass the first st over the 2nd one. You would pass the st over both the st and the YO - I think. The instructions aren't really that clear.
Knit 2, then YO, you have 3 loops on the R needle. From the tip they're 3, 2, 1. Pass st 1 over the other 2 which leaves sts 2 and 3 on the needle. Then YO twice and pass stitch 3 over the double YO.
Do you have a link to the pattern, or to a picture of it? That may help figure it out a lettle better.
