Patrick,let's look at the time-like part of the commutator in a different way.The commutator implies that [tex] \Delta E_1(x_1,t_1) \Delta E_2(x_2,t_2) \geq \hbar(...) [/tex],i.e. field measurements E1 and E2 at two spacetime points follow the uncertainty principle.So if I make a measurement at x1,t1 and find a certain value,the value at x2,t2 is totally uncertain.But if I make a measurement at x2,t1 (or near about t1),the value of the field is certain.So you are also right and so is the disturbance model.
