It seemed to me that Louisoix's halting of Bahamut did enough to prevent a ton of damage, so rather than having to wait, the Ascians were able to speed up. As for why they keep escalating and refuse to wait for us to die however...we can blame Nabriales for that.

He was explicitly told by Elidibus to not engage us, as we were potentially no longer a threat after losing our Blessing of Light, and might have had the way to kill them. They could have waited things out from that point on and possibly won because we'd never get a chance to try it out. But because Nabriales lunged for us, we discovered how the trick worked, and possibly could have developed a method to reach them in the Rift from there. It became a race against us to succeed in the next Rejoining before we found a way to halt them for good. All thanks to an overzealous Nabriales.
