Please, note that F02ElectricFieldSetup::UpdateField() does the following:
(*) Chooses a G4MagIntegratorStepper for your simulation
(*) assigns your field to the G4FieldManager
(*) instantiates a G4MagInt_Driver
(*) assigns the G4MagInt_Driver to G4FieldManager
It is beyond me why you think you need none of this simply because your E-field is in a different direction than the example.

Good question! This may be unintended and could be changed.
