To brute-force sense into something that was not intended to make sense in this context, maybe the Second could make it so that all of those worlds with their differnces were in that point in their history a single timeline, and Zelretch used that temporary connection to use all of their mana at once and defeat all the moons.
But that would require him to also make all the moons into one moon and then the math gets weird
