With some fish you have aggression towards each other...and you can minimize that by boosting the numbers. That way they aggression is distributed and one fish doesn't get the brunt of it. That is the theory behind grouping some cichlids together.
Somehow I doubt the same applies to a great predator like an Ornate. They have the potential to be 2 feet of predator. Big predators tend to not like to share space. People who house multiple bichirs in numbers unfit for them don't do it because they are trying to distribute aggression. They do it because they are A: Ignorant, B: Treat their fish like decorations, or C: Are caught up in the thrill of having a "Predator" tank and don't care about the well being of their fish so long as they are big and cool to show off to friends and the online community.
Anyone who wants to keep an Ornate has no excuse to be keeping two of them together unless they are trying to breed them. Even then you want to be careful. Honestly you should try to replicate the conditions, and introduce the pair long enough for breeding and then separate them to minimize risk of aggression and or injury.
