No I don’t think that’s right: When a light wave enters the new time interface and the device changes its optical properties, the signal keeps moving forward in space. However, the signal gets reversed—if it were a spoken word, it would sound as if it were getting played backwards. In contrast, with a conventional reflection, a light or sound wave would travel back at its source but mostly look or sound the same as it did before the reflection. — They continue forward, but they behave in the reverse with respect to time alone.
