Good question,
Let me start by pointing out my mistake in pursuit of this badge, playing this at maximum volume while defeating the two will NOT get you the badge, and will only annoy your neighbors.
According to this guide, you cannot pull them during any phase of the trial to get the badge.

Shoot on sight, please.
Thanks Ulli - indeed we toasted Nightstar and Siege in their spawn points and walked away with Master of BAF! Thanks to all who participated. Then we broke BAF! And kept getting more than 24 team members when trying to enter trial and instead would enter someone's mish. Very aggravating.
I was there too... we all got transported to an AE mission when we somehow had 25 ppl. We had a great group though, we kicked some butt for sure.
In case you hadn't found out already you cannot move the AV's from their spawn points at any time and get the badge. Last night we had Siege move about 100' from his spawn point during the final beat down and the badge wasn't awarded. I'm not sure what the exact tether range is but when he ended up about halfway between his spawn and the gun tower directly across from him we didn't get the badge.

I got the Badge today on McArchvillain. And NightStar did move around some. But never got off the "Sidewalk" nor past the buildings. Not sure if that helps any. And yes he did get MoBAF.

I have a couple questions for those of you who have gotten the Master of BAF, in regards to the "Gotta Keep 'Em Separated" badge, where you have to "Defeat Siege & Nightstar without moving them from their initial locations during a Behavioral Adjustment Facility Incarnate Trial."
Does this mean that Nightstar needs to be taken down where she spawns, then defeat the escapees, then Siege has to be taken down where he spawns only, and then when they both rez they can be pulled to one location? Or, does it mean that after they rez they need to be again defeated in their original locations, i.e., "Gotta Keep 'Em Separated" both times?
