I think he means "class reference members whose lifetime is determined by 
the lifetime of the object that refers to them.  i.e.

class A
{
    auto B b;

    this()
    {
        b = new B();
    }

    ~this()
    {
        writefln("A dtor");
    }
}

class B
{
    ~this()
    {
        writefln("B dtor");
    }
}

void main()
{
    {
        auto A a = new A()
    }
    writefln("Done");
}

Would print

A dtor
B dtor
Done

(Or maybe the order of the dtors would be different, but the point is that 
the instance of B's lifetime is dependent upon the instance of A's.)
