Just to follow up, after a little more research:
FACET means the entire triangle, not an individual vertex. STL files are
composed of flat triangles, not smooth ones. Giovanni's STL image show this too.

-------------------
I am not very happy that MESHMIXER (and CURA) show 'smooth triangle' versions of
the file; I would rather see the raw-triangle representation there. And it seems
that CURA also *outputs* its .stl-to-.gcode 3-D-printing file as a
smooth-triangle version, according to tests that I have made. I have mixed
feelings about that...
