In general, is it ok to give a function and items returned by the function the same name?

Personally I think it is confusing but I was wondering if there was a reason why both the function name and the first item returned by the function were both named "greeting"

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

    return greeting
}

var result = greeting("Tom")
println(result.language)

It is valid, but I am guessing that it is not advisable to use the exact word for both the function name and the name of one of the vars or constants within that function in practice
