Close but not quite..

The O/P has a year-long, multi-entry Non-OA <- the A after the O is important π That visa is good for unlimited entries while the visa is valid for, and every entry on that visa gets stamped in for a year (or as long as the mandatory health insurance is valid for up to a year).
Most people get two years of stay out of that visa by exiting/re-entering just before the visa STICKER expires, that gets them stamped in for another 'free' year. <- Now if during that year (after the visa sticker was expired) they wanted to exit they would need a re-entry permit and they'd get stamped back in to the original expiration date they got before. <- you don't get any more time than that out of the visa
