This control will certainly control for DNA contamination present in your
reverse transcriptase.  However, you are still depending on your RNAse A
to work (probably not a huge issue :-)).  Also, it does not control for
DNA contamination present in your RNAse A.  I think you probably need
both controls to be really thorough.
