remember, there's a difference between gens and stages, so the poses might be on stages 3 and 5, but all gens will go through those stages. also, depending on the item's evolution rate and how long ago it finished, the third gen may have already finished evolving and will no longer do so, or the third may have awhile to go before it finishes and may be past that stage. so I guess the answer is a combination of A and B

in the above image, if you were to buy the third gen at week 4 but the poses you wanted were from stage 1, you would have to wain for the item to finish. however, if it was week 6, the third gen would already be fully evolved and would already have all of the poses.
hope that made sense
