I'm 100% sure

it works like this; the OA visa is valid for a year, it is good for unlimited entries for that year. Every entry gets you stamped in for a NEW year (as long as you have health insurance coverage).
So you enter, get stamped in for a year, then you exit/re-enter the country just before the VISA itself expires (a year after it was issued). That would get you stamped in for a whole NEW year <- giving you two years of stay out of a visa that is valid for one ๐
Many many MANY people who have had OA visas have gotten two years of stay out of it. That's one of the reasons (beside banking the money in your country) that people get them before they come here
