I've never liked handwaving things with the Echo; I assumed that Louisoix pretty much sent every living non-Garlean on the field forward, because even John Failspear the Level 0 Crowd-Surfer is going to do more good in the distant future than the immediate future. (The immediate future at that point consisted of getting killed by Bahamut.)
By my reading, at this point Louisoix had a lot of power without a lot of scope or time. He had the physical strength left for one more cast (funneling the power of gods through a mortal body is always going to result in some serious fatigue, just like running 10 gigawatts through a 6 watt fuse), and he had to make it count. So he scooped up everyone in range and shoved them forward.
Of course, that's only half a step away from assuming everything just works at the speed of plot. (Who did he pick to send into the future? All the people that got sent into the future. Doy.)
