I am unsure what OP mean also.
Regarding the story, this is pretty darn big news. I will be watching for more news over the next couple of years to see if the data remains constant. It could still be some naturally occurring phenomena which we have not seen yet, perhaps some particularly thick dust cloud of unusual composition. If it is natural, the data will change over time. If the data does not change, then yeah, we are probably talking about a dyson sphere.
The distance is significant. We won't be seeing astronauts reach there structure in our live times or anything of that sort. The change will be a much more gradual acceptance of intelligent life elsewhere in the universe, much like how the evolution of species slowly caught on in the public over the course of several generations.
