Why are some comments highlighted (or "greylighted"), e.g. the three in the middle, and some are not?

Is it something to do with my instance (lemmy.ca)? Their instance? Invidividual users?

Confirmed. I just opened a post I'd never opened before, and one comment was highlighted. It had been posted just four minutes earlier, so perhaps it is determined by a time limit.
