With that 240V, single phase, tandem breaker set up all hot wires are connected to the breakers. Grounding conductors(bare or green) are connected to the ground bus in the panel. The outer two hot wires go to one appliance, the inner two to another. This is important because on an over load the inner two breakers are tied together mechanically, and the outer two are also tied together. So in the event of an overload all hot conductors to a load are interrupted because of the mechanical tie between the breakers. It doesn't make any difference which breaker the red or black conductors are attached to as long as the ones from one load are connected to the inner breakers and the other load are connected to the outer breakers. A bit confusing, but if you think it through it makes sense.
