I still don’t understand what Barbour’s theory actually says, and if it says anything at all. It seems to be one of Eliezer’s more bizarre endorsements.
Does this explain it for you, or are you looking for something more detailed?
Barbour is speculating that if we solve the Wheeler-DeWitt equation, we’ll get a single probability distribution over the configuration space of the universe, and all of our experiences can be explained using this distribution alone. Specifically, we don’t need a probability distribution for each instant of time, like in standard QM.
