I've wondered the same and thought they might be new since my last visit?

I just entered the thread, so in that case all the comments should be highlighted.
So they're supposed to mark the new comments that we're created less the 10 mins ago. I'm not sure why you're seeing the other comment highlighted when it's a few hours old, did you follow a link to that specific comment? If so, that comment will also be highlighted
I didn't follow any links.
Update: the limit seems to be 4 hours for comments, not 10 minutes.
Thanks for the update, where did you find the 4 hours documented?
I didn't, I just noticed that 3 hour-old comments were highlighted, while 4 hour-old comments weren't (but I just saw a highlighted 4 hour-old comment and an unhighlighted 3 hour-old comment, so it might be something else).
