Yes that is how it works.

"The criterion for the awards states, "In the spirit of Charles Darwin, the Darwin Awards commemorate individuals who protect our gene pool by making the ultimate sacrifice of their own lives. Darwin Award winners eliminate themselves in an extraordinarily idiotic manner, thereby improving our species' chances of long-term survival."[2]

Accidental self-sterilization also qualifies; however, the site notes: "Of necessity, the award is usually bestowed posthumously." But the candidate is disqualified if "innocent bystanders", who might have contributed positively to the gene pool, are killed in the process."
