In the paper they show how their technique can measure steam quality to within a few per cent between 5% and 80%. 5% corresponds to 5 % steam by mass, and yes, that means 95% liquid by mass.
That seems to be the official definition of steam quality: mass of vapor divided by total mass. So 0% quality means pure liquid, 100% would be pure vapor, "high-quality steam." However, people have been referring to the inverse, the percentage of steam that is liquid, creating, possibly, come confusion. Dry steam is 0% liquid by mass.
