Why the code only use "this" keyword instead of "this.names" for indexers property?

Question

class Clients {
private string[] names = new string[10];

public string this[int index] {
get {
return names[index];
}
set {
names[index] = value;
}
}
}

Answer 1

If I'm not mistaken it's because the names are in the get and set as "names[index]"
