Why is the function name "greeting" and the constant name "greeting"? Isn't this bad form to have them named the same?

tuples.swift 
func greeting(person: String) -> String {
    let language = "English"
    let greeting = "Hello \(person)"

The constant name 'greeting' only exists inside the function, this is called scope. So they will not conflict.
