Legend
While that is how it reads, I think it is fairly obvious that if this is a mythic creature that the mythic trait overrides anything like disintegrate of chill touch. Think of it as the old immediate interrupt (was that thing in 4e or am I think of the old interrupt cards in MtG?), basically, whatever brings the mythic creature to 0, if there are additional riders, its effects are interrupted by the mythic trait (or the cutscene as someone mentioned earlier).
