Bruce, I mean that within each branch, the observer experiences making a definite choice and can't predict which branch they will end up in before decoherence.
Globally, all branches are determined, but subjectively each observer sees only one outcome and experiences it as a free choice. This is similar to how in classical determinism you can still feel free even if everything is fixed in principle, except here all alternatives coexist rather than only one. Quentin All those moments will be lost in time, like tears in rain.
