So if the planet explodes and the person that is on the planet survives, then they did not withstand a planet busting attack?
Did explosion that destroyed the planet originate from right next to the character? Did the explosion originate from the core? Did it originate from the other side of the planet? How large was the explosion? Was it many times larger than the planet it destroyed (An example you would be familiar with is Kid Buu's blast that destroyed Earth, which IIRC had an explosion larger than Jupiter)?
This has to be determined on a case by case basis.
