There is a chance the seeds will just sit there and wait for the cool period. And there is a chance (as not a number stated) that they will (or some will) go ahead and grow. It's a gamble. If you are going to grow inside under lights, it doesn't matter what outside the season actually is (since you will control photo period and temps). If you want to grow them outside, then sure, it could matter and may pay off to go ahead and treat them as if they already had dormancy. If some grow and some down, the others may sprout next spring after the cold period.
