Question on the set-in sleeve

A question on this pattern: I've purchased it, but I have a question on the set-in sleeve. The photos on the envelope both look different. The blue version looks like the set-in sleeve is meant to fall off the shoulder, not hit right at the top of the shoulder. While the yellow top looks like the sleeve seam is meant to hit right at the top of the shoulder. Is this correct, or is the model just wearing a smaller-size pattern in the yellow version? It sure fits her differently. I would like to know how this is designed to fit before I cut it out in my fabric, if someone could take the time to answer my question. Thank you!-- Gail
