Ok the instructions read:

Join Sleeves to Body
NOTE: Read through this entire step before beginning.
Using circular needle and ball of yarn attached to body, and working in 1x1 rib as set, work across 40[46, 52, 58, 62, 64, 76] sts of one sleeve, work across 60[66, 74, 82, 88, 96, 108] sts of front of body, work across 40[46, 52, 58, 62, 64, 76] sts of second sleeve, work across 60[66, 74, 82, 88, 96, 108] sts of back of body. Place marker to mark beg of round.
There will now be 200[224, 252, 280, 304, 320, 368] sts on the circular needle, and the sleeves and body will be joined, ready for the yoke to be worked. At the underarms, the sts on waste yarn from the body and from the sleeves will be opposite each other. These sts will be joined later on.
I'm not sure how this is supposed to go. Wouldn't this cause a huge stretch between the stitches on the body?
