I was always puzzled by the significance and mechanincs of that scene but now, it all makes perfect sense, the WoL back then inadervently drew on their 'wanderer' powers and summoned their closest allies to them without even knowing it to help them defeat Lahabrea (and it was probably also boosted by the WoL being right next to Hydaelyn herself at the time). And given EW will be the resolution to that story, it would make even more sense to see this very thing one more time as a call back and fitting coda to ARR's beginning (alas, 1.0 had nothing like that).
