Need clarification - K&B book

[Meena R. Krishnan]

Page 36 - Protected Details

The bottom line: when a subclass-outside-the-package inherit a protected member, the member is essentially private inside the subclass,such that only the subclass and its subclasses can access it."

As per the statement, if it is private inside the subclass, then how the subclass' subclasses access the private of its parent class.

package PackageA;
 
public class Parent {
protected int protectedMember=333;
}
package PackageB;
import PackageA.Parent;
 
 
public class Child extends Parent {
private int privateMember =555;

public void printParentsProtected(){
System.out.println( protectedMember);
}
public static void main(String[] args){
new Child().printParentsProtected();
}
 
}
package PackageB;
 
public class GrandChild extends Child{
 
public void printParentsProtected(){
System.out.println(protectedMember);  //can access grand Parent's protected member
}

public static void main(String[] args){
new GrandChild().printParentsProtected();
}
}

My doubt is only in the statement.

I think you're right, the member is not really private. But for that reason the authors wrote

the member is essentially private inside the subclass

because they wanted to point out, that no other class (excluding subclasses) in the package can acces this member. One could think: ok the inherited member is a protected one, so all classes in packageB (convention: package names always begin with small letters) can access it. The authors made clear that this is not how it works.
