Need help with "Pinup Queen" shoulder shaping

[Holly]

I'm currently making "pinup queen" from Stitch n Bitch, and am totally perplexed by the shoulder shaping directions. I've basically got a shape like this:
=================
XXXXXXX XXXXXX
The === line is the back of the neck that is being done kind of like short rows (stop and turn) leaving the X stitches on either side. This is the direction: "with WS facing, attach yarn to neck edge of left shoulder sts and complete row. Attach 2nd ball of yarn to neck ecge of right shoulder. Working both shoulders at one time, BO 2 sts from each neck edge twice, then BO 1 stitch every row twice. BO rem sts." Am I binding off where the X's meet the == ? Thanks in advance :-) Holly (PS I've been offline for a long time, and it is nice to be back on KH!)
