Why is the "Eliminate duplicates" button is always greyed out?

Hi,

This has already been asked once, http://devnet.jetbrains.com/thread/441091 and even answered, but I really can't understand the answer. Does "..., so this was disabled." mean that it just does never work?
To test, I've created simple class with two methods:

public void method1(){
        for (int i = 0; i < 100; i++) {
            System.out.println("aaa");
        }
    }

    public void method2(){
        for (int i = 0; i < 100; i++) {
            System.out.println("aaa");
        }
    }


it finds the duplicates, but the Eliminate is still disabled. Does anybody got it used?


Best regads, Eugene.
