This article isn't really about the practical implications of pondering death or of maintaining a philosophical, cosmic perspective that emphasizes our mortality and humbles us in the process. I'm not saying the enlightened individual must be constantly melancholy and misanthropic. We can imagine Ecclesiastes' more pragmatic response to our mortality.

You're seizing on the article's last line, but the main point I wanted to make was about the existential test of thoughts and behaviour: Are they worthy, given a death-bed perspective? We can ask ourselves that sort of question throughout our life by imagining whether we'd approve of our conduct if we were on our death bed. My suspicion is that that's roughly how enlightened individuals think, at a minimum, even if they naturally have their theological, metaphysical, or other doctrinaire ways of handling the existential confrontation with their mortality.
