It's explicitly clear in the article that this isn't "instantaneous" travel. As much as I hate the analogy, they basically were able to copy the box, the cat, the Geiger counter, and the radioactive trigger wholesale and transmit the copy somewhere else. Normally the process of copying would mean someone had to look in the box. This time they were able to copy the package without finding out if Heathcliff was alive or dead.
