Are you possibly thinking that the landmass that the aircraft is flying over is Russian territory? It is actually flying over Norway. In the image below I colored in green the border between Russia and Norway, and in red the border between Russia and Finland.

The closest that it got to Russian landmass appears to be about 28 nautical miles (32 miles, 52 km). As mentioned in [another answer][2] to your question the limit is 12 nautical miles. And as mentioned in a comment by @Bianfable, [OpenStreetMap][3] shows this boundary.
