Still do not understand 'change'

In your first example, a single character at position 3 is different; and thus you call this "Modification".
In your 2nd example, three characters at positions 13-14-15 are different; and this is also a "Modification".

What if 20 characters are different? Is that simply another Modification? When is a Modification not a Change, but a delete and add?
