That's how I understand it, as well. And when it does go Supernova, it's too far away to do serious damage to Earth. It will give off enough light to be as bright as a half moon for about a month. It will even be visible during daylight, but the blast wave will dissipate to almost nothing by the time it reaches us. We'll just have really nice aurorae for a few years as the stellar remains wash over our Solar System (centuries after we see the Supernova itself, since what's left of the star will be traveling below the speed of light).
