I saw some analyses on YouTube on the scenario (which I still haven't figured out why I'm watching), and they mentioned the possibility that it would fall under that. But Roshi already died from the Evil Containment Wave, which wasn't considered natural, so it's possible that dying from an overdone Kamehameha also would be wishable.

Different balls. Roshi died when Kami was still around.
