What you mentioned is correct for three-level scheme. What is the advantage of fourth level?

comment The difference between the Wannier function and atomic orbit in a tight binding model
My comment is not against DFT. And technically your answer is more or less correct. It just looks strange when something relatively simple is explained using something much more complicated.

comment The difference between the Wannier function and atomic orbit in a tight binding model
It is quite strange that you are trying to explain what Wannier functions are by using arguments from DFT. DFT itself is an approximation which fails in many cases.
