From what was explained to me, this badge represents the situation when two people post similar answers at the same time. While both are correct, they don't add anything new. It rewards a user for recognizing this situation and being disciplined enough to delete their answer. Of course, once you get the badge, you can undelete it without losing the badge.

The devices tag is no more.
