Error in pattern?

I just bought the Noro book that has the Ekeby Vest pattern. On row 13 the directions do not look right. Row 13: Bind off 6 sts (k4, bind off 8sts) 4 times, end with k10. All of the other rows start with k4 or k10 but this is the only row that starts with a bind off. Is this correct?
Thanx

For those on Ravelry, here’s a picture. You BO to make the holes in the vest, it’s a really different construction. So just ‘trust the pattern’ in this instance.
