I'm also going to say that it isn't a plot hole with everything that has been said.

In addition, I thought of another reason. It isn't uncommon for an enemy to leave survivors to speak of their terror and what they did. There are plenty of real world and scifi examples. One of the ones I can think of is Malak leaving shuttles after he bombed Telos to oblivion. Mentioned in KotOR II.
