Not sure how to answer you.
What can one say about a given martial culture, esp from a distance of so many years?
I would guess that for whatever reason the JSA simply found the 2 handed weapon to be very useful for their given combative situation.
I could speculate, but that is all it would be.
BTW, the sword in each hand thing--although many ryu had such techniques, they were not often used.
Even the Niten Ryu seems to use the 2 handed grip (instead of a sword in each hand) on many of their kata.
