I would assume because it's right in the actual surgeon's view instead of requiring constantly moving the head to look at the monitor, then look at the patient.

Better title would probably be "First Ever Virtual/Augmented Reality Assisted Surgery"

Ah, for some reason I was imagining this on the side of the remote expert rather than the surgeon in the surgery room. Makes a lot more sense, now!

That's correct. During open (non-minimally invasive) procedures in which you're being virtually proctored, you want a head-mounted camera and display. This is because if you have just a head-mounted camera, every time you look up at a monitor to receive instruction your camera's field-of-view changes.

And that was roughly the original title, pre-editing.
