I just checked my magazine and I think I know the part you're talking about. It is correct--you're doing a series of decreases & increases that require 6 stitches--
ssk (decrease using 2 stitches), yo (increase--don't count this as one of your 6 since it's in addition to those!), ssk (uses 2 stitches), k2 (with last 2 stitches)
So maybe you were counting the yo? These are kind of vague instructions--cute bolero though! I was thinking of making it too.
