I haven't listened, but did they say the "water content" or "moisture content" was 140%?

It is calculated as the mass of water divided by the mass of the soil. (you weigh a sample, oven dry, weigh again)
So, a saturated sample of a very light weight material could have a water/moisture content over 100%. It wouldn't happen with a natural material.

very similar in concept...

... to a super-saturated solution.

he was speaking about the

he was speaking about the water content of the ash/sediment layer. I don't necessarily question that a relative saturation content could be over 100 but not a content.

Well, "water content" in

Well, "water content" in this context is a specific property used by soil engineers/scientists that can be over 100%.
Taken out of this context, and in lay terms, it would seem to most people that a "content" could not be over 100%.
