He obviously meant that you can't get a pointer to the object, that the
reference points to, just by casting and w/o address-of.

   int* f(ref int r) { return cast(int*)r; }

   void main() {   
      int a = 42;

      import std.stdio;
      writeln(&a);
      writeln(f(a));
   }

Yes, this will compile, and, yes, you can "cast a reference to a pointer",
but this does not mean that you will get a pointer to 'a'.

The D situation wrt to refs and classes is bad enough; saying that you
"can cast a reference to a pointer" will only confuse people.
