clarification regarding one of the rules of overriding given in scjp 6 study guide by Kathy and Bert

Hi
Did not know if needed to start a new topic or continue an older topic of mine but started a new one.

In the Rules of overriding given in scjp 6 study guide by Kathy and Bert (pg. no. 106)

The rules of overriding a method are as follows:

(5)Instance methods can be overridden only if they are inherited by the subclass.
A subclass withing the same package as the instance's super class can override any superclass method that is not marked private or final.
....
(6)...

In this post in the case 1 -

The Class C3 does not inherit the method met1() from the Class C1, but it overrides the met1(), since met1() is visible in class C3.

So my Question is that rule - a general rule as mentioned in the book ? as I see a contradicting case above or am I missing something.

Thanks in advance

Inheritance and the overriding of non-private methods does not
depend on the class packages. So I am confused about how you
see them linked. Can you explain further? Thanks.
