Does using listerine after brushing teeth with whitening toothpaste prevent whitening from working?

I have a five-minute teeth-brushing routine:
1. Floss
2. Use Anti-Plaque Before-Brushing Rinse
3. Brush with with toothpaste with whitening agent (Crest, etc.)
4. Rinse with Listerine with Anti-Tartar control

Does using the Listerine mouthwash wash away the whitening agent and prevent it from working? I know off-the-shelf whitening toothpaste does work miracles, but I haven't noticed much whitening after months of using it...
oops, mean't "doesn't" work miracles...
