Yep.
There isn't anything in particular in saliva which will add a beneficial property to paint. You are basically just adding/maintaining moisture. You don't want to just use a cup of water (though you can with certain paints) as excessive amounts of moisture will ruin the particular technique.
The exact technique will vary some - but basically you use one brush to effectively transfer paint - then you use a second clean but moist brush to move it about (and create the transition surface). Too much water and it becomes a mess. I use a sponge which is sitting in a reservoir of water (just a small dish). It stays wet and keeps the brush wet and ready to go.
