Confused - pattern James Brett 669

Great pattern for ladies jumper. But last bit of sleeve instructions cast off 9 stitches for 4 rows leaving 10 on the needle.
However these 10 stitches are not referred to in the making up section. Had anyone else seen this in a pattern?

Welcome to the forum!

These instructions might occur in a saddle shoulder sweater but from the photo, that’s not a feature of this sweater. Check the instructions for finishing or making up the sweater and if the remaining 10sts aren’t mentioned, go ahead and bind them off.
There is a nice way to bind off all of these sts without a “stairstep” edge.
