Why is it possible to get the same award more than once?

I’ve gotten the “Starfish” award 8 times. Why is this possible?

I know I’ve gotten it 8 times because I moused over the starfish award here:

And it says:

Get a Great Answer on a new user’s question.
—“A starfish-a-day keeps Dr. Jelly away!”
(Awarded 8 times)

Now obviously the award has got to have been awarded more than 8 times total for everyone because this thing has been going for a couple years. So I’m thinking that it’s been awarded to me personally 8 times. So, why is is counting? Why not just have it award it once and be done with it?
