   Can anyone throw any light on these?

From the diagrams that have shown up in the articles I've seen so far,
it looks like there are two outlines per parameter (weight, etc.),
and an actual font is generated by interpolating along each such axis.
This does not involve a lot of computation, but requires some care in
designing the actual letterforms, since all of the control points for
a particular character must correspond in all variations of it.

It may be more complex than this, but even if this is it, it's still
pretty clever.  Not up to Metafont, but very useful at a relatively low
cost in complexity.
