Help with instructions.

The pattern says row 1 K to 3 sts before the center BOst, k2tog,k1. Would that the be 4 sts including the BO st? If so that leaves one unknit st.
Thanks.

The bound off stitch leaves a small gap. Knit to 3sts before that gap, k2tog, k1. Then you’ll have no more sts left before the gap.

Thank you! I get it now.
