I agree that it is a weird take, but your analogy is off. The actual therapeutic effect would be stopping suicidal ideation, not a single instance of suicidal behavior. A person may continue to suffer whatever ill effects that were pushing them to suicide but (temporarily) reconsider the action itself. On the one hand, nobody can "fix" you; you need to internalize different ways of thinking and build emotional resilience. Drugs may help this process, or help maintain it, but they're not a cure, and neither is talk therapy. It is, in a sense, a matter of convincing yourself. On the other hand, most people- even very introspective people- will struggle with self-therapy. It isn't as easy as "today I am happy".
