Because that's saliva on our fingers not actual water.

Paper becomes more tactile when wet. So we are increasing the grip of the paper as it absolve a water.

And your fingertips become more grippy when you hydrate the skin...

It's because the moisture raises the adhesion of paper (and other items) to skin.
