It's more like a tsunami of Running Balances vying for event horizon. I'm not sure how this is ever supposed to be "consistent" unless you're talking about full historical nodes, in which case yes definitely, but non historical nodes are able to prune transactions after a while. Still a lot to dig out of this gem of a paper, any error in interpretation is my own.
