It's always from our PoV.
We have no idea and no way of knowing what's actually happening 600 ly. away, right now.
All our measurements are based on the light and radiation we can observe from here. We have no sensors close to it.
So if the paper is calculating supernova in couple of decades, it means the star actually went supernova 600+ years ago.
