If you plead for the grim reaper as an elder what happens?

I've had one sim successfully be granted more time by the Grim Reaper and he was an elder. He happened to be a gay sim in a long, happy, monogamous marriage. Literally, he never even looked at another sim romantically other than his spouse. (He happened to be a geeky, techie guy - an INTJ type, probably, and other than falling in love with one man, he didn't focus much on romance. He didn't even necessarily want a child but his husband wanted to adopt and organized that. They were a very happy and stable family.) Anyway, he was granted more time probably as a result of the pleading of his husband. It's been a little while since I played them.

I know that it just meant that he got a few more days. He ended up dying on the same day within an hour of his husband. They are buried together in my makeshift graveyard in Newcrest.
