The writer states "Suicide is when severely depressed people choose death over life." That obviously is your opinion, but a dictionary definition is simply: "suicide |ˈsoōiˌsīd|noun  - the action of killing oneself intentionally". Among other problems I see with this proposal, the allowing intentional false statements on official documents (defining this as other than suicide on death certificates) is dishonest and deceptive. If this is a valid, acceptable choice then call it what it is, don't lie about it.
