As far as I understand yes, I would also guess that it is analogous to a phased array antenna, but with sound waves

It's a sound laser, or maybe I'm remembering the video in this link wrong on the terminology and the SASER is different? Maybe it's just "sound from ultrasound"

This is not a sound laser; the beam has some similar properties to a laser (e.g. collimation), but it works more like a directional antenna.

Yeah I think you're correct. Really interesting distinction

Its quite interesting. The directional ultrasonic array broadcasts a carrier frequency, not unlike am radio. You can read about the function of this sort of device at hackaday.
