I should also point out that this is a very different design concept to using "loosely" coupled windings to offset the effect of a shorting cap.

Yes. they seem to be using a design that uses a loosely coupled winding is series with a cap across is.
I tried in spice to get this to work but was unable to get anything near flat results. I still do not see how this idea would work.
