there appears to be something that looks like a third black hole or sphere in the center between the two black holes, and it is of the same size; wonder if that is an artifact, or part of the simulation result

Physics is amazing. It is amazing how a sophisticated computer animation of the event on a grand universe scale can look just the same on a small scale. I get the same swirling pattern when I put two electrical mixers in a bowl of batter with food coloring thrown in.

At 30s, the video displays a text that 'this region is not modeled in current simulation'. Hence, it is an artifact of the current simulation.
Wrong Music!

https://en.wikipedia.org/wiki/In_the_Hall_of_the_Mountain_King wrote:
<<"In the Hall of the Mountain King" (Norwegian: I Dovregubbens hall) is a piece of orchestral music composed by Edvard Grieg in 1875 as incidental music for the sixth scene of act 2 in Henrik Ibsen's 1867 play Peer Gynt. The English translation of the name is not literal. Dovre is a mountainous region in Norway, and "gubbe" translates into (old) man or husband. "Gubbe" is used along with its female counterpart "kjerring" to differentiate male and female trolls, "trollgubbe" and "trollkjerring". In the play, Dovregubben is a troll king that Peer Gynt invents in a fantasy.
Grieg himself wrote "For the Hall of the Mountain King I have written something that so reeks of cowpats, ultra-Norwegianism, and 'to-thyself-be-enough-ness' that I can't bear to hear it, though I hope that the irony will make itself felt.">>
