My guess would be that the wet cloth catches many of the smoke particles,

Based on the one referenced FAA article, the dry cloth does nothing for
safety, but a wet cloth reduces the water-soluble hydrogen cyanide gases.

In WWI, early in the gas warfare stage before there were gas masks,
soldiers wet cloth with urine, which apparently absorbed chlorine and
phosgene and stuff pretty well. It's better than dying, I suppose.
