Found it. It’s the instruction directly before the yoke. So you have 5 and another 5 stitches on the sleeve and these will be grafted to the 10 from the body that you are now slipping onto yarn. You can go directly from your current row, transfer the 10, and knit the sleeve stitches keeping the working yarn tension even as though those 10 don’t exist. Later on you go back to graft them under the arm with the 5 + 5 left in yarn jn the sleeve.
I’m pretty sure this is right.
