LOD and Tesselation are different effects. LOD requires making more then one model, tesselation does not. Tesselation is mapped onto the model, so you could use 1 model and have its polygon count gradually increase as it gets closer. LOD is not gradual it switches out a low count for a high count model at distance which creates often a "popping" effect. Also it should be noted LOD means either the game has to page the harddrive, or you store the models in your ram which takes up space, which tesselation does not.
