I think that white and blacck are good representations of their style, and I would prefer a white over almost any wit on the market.
The Curieux, the Hugh Malone, the Fluxus... Honestly, Allagash is at the top of their game. They don't screw up much.
As for the OP. The different stages of fermentation probably have to do with when they add the sugars. What I could see happening is them doing the initial fermentation, then adding one sugar and a new strain of yeast. And then repeating that process.
As for the malt and hops bill, I am sure if you look up a fairly normal quad recipe, the malts would be close. I'll have to drink it again to even guess at the hops, but I'd probably be wrong.
You should email them. Brewers are pretty good about answering questions.
