Problem on as1tester.c, Maybe BUG

I just tested my code by using as1tester.c, but I found some problem with test 9.23. It said "Test 9.23: io_edit() Escape when IsTextEditor = 0, hit HOME key, then 'a', 'b', 'c' and then ESCAPE to test!", but it would be always failed because it required everything equals default value, I mean, nothing was allowed to change. So if you hit HOME KEY and insert three letters, that's impossible to pass the test. Therefore, I think there is a bug here.
