I would reckon that the aisleway between the seats helped channel his adversaries into a linear target. Once one went down, he then had access to the next one, and so on. And since he was presumably lacking body armor, holding up the sliced and diced carcass of the first one he had dealt with made an acceptable field expedient substitute, as well as presenting a nice example to the others as to what was coming their way.
AYO GHORKHALI!
Somewhat like the pass at Thermopylae channeled the Persians for the Spartans.
