Yes, the first year of the match for vascular neurology was last year. This should make it such that the timing of your interview isn't hugely important, but I can tell you that many programs didn't play by the rules last year. I heard rumors of several programs offering spots to the top applicants somewhat unofficially prior to the match. Given this knowledge, I would still recommend trying to interview early. Hopefully these few programs will shape up, but I think they have little incentive to do so.
