It's hard to read between the aggrandized lines, but it appears that this is a discrete phenomenon based on precisely switched gates/reflectors. It's super interesting but not exactly science fiction.

Imagine your signal looks like _A_B_C_ where each letter represents a discrete subpacket. The reflectors look like _1_2_3_. As long as those gates are timed to turn on precisely between the subpackets, the reflected signal would be the reverse order of packets.
