Yes, you will bind off where the XXs meet the ===s on each side. That will be where your head will go through and you are shaping that neck opening a little. The general rule is that you do bind offs at the beginning of the rows each time. It doesn't work to bind off at the end of a row if you BO more than one stitch. So on one side you will be making your bind off 2s from the front side and on the other side you are binding off 2s on wrong side rows. These bind offs of necessity will be every other row.
Then it says to BO 1 stitch at the beginning of each row 2 times. That is technically possible but I like the look of it better if when you are only taking off one at the neck edge of each row to just work them as K2 togs or P2 togs depending on which side you are on. It accomplishes the same thing and I think it is smoother.
I know it says to work them at the same time, but sometimes that confuses me and I prefer to work one side and then the other following the directions carefully on each side. But if it works for you you can do them at the same time.
