In simulink model, in 3 level Neutral clamped Inverter they are taking positive half dc voltage and negative half dc voltage w.r.t neutral?

And giving it to a MUX and again to demux and then subtracting +Vdc/2 and -Vdc/2 and again giving it to a gain of .5. Why these are required? Why that .5 again?
