If I understand correctly it is designed to operate for a short time (destructively) in space, but this test happens on Earth, presumably in normal atmosphere. I don't know the size but Gizmodo says it was at an altitude of 23 feet.
I see a "main" thruster to maintain altitude (in the test, against Earth gravity), and a "left" and "right" thruster for translation and stopping, and four diagonal thrusters for "fine positioning", perhaps? Although the axes of the top pair meet above the spacecraft axis, and that of the bottom pair meet below, so perhaps they add translation and torque simultaneously?
No matter though, it looks like all thrusters lie within a single plane of symmetry.
The attitude seems quite stable throughout, even after falling and landing. By the way it moves, does it look like it has rotating intertia wheels of some kind, to maintain attitude?
The YouTube video shows the same 30 second test "flight" from three different angles:
