Firstly, I'm pretty sure that it is yield that is measured in teratons, not range. That said, the Halo Legends' relationship with canon is apparently VERY flimsy: that very episode apparently has a Prophet killed before that happened in canon & some of the details are outright stated to be artistic interpretation (like the Spartans' hair length, etc.)

Finally, even if all of that is canon, just how large was the area hit by first shot (or the ship cut in half by the second beam)? The first one seemed as little as few tens of metres, IMHO, and if that first beam was anything like the second, then most of the destruction would have been concentrated at the epicentre, while the 80% percent of it would be survivable by Ork vehicles (and 20-30% by infantry). All in all, I don't really see this as a gamechanger.
