Instead of calling xgifb_reg_and_or with almost identical parameters in a simple if/else scenario, we assign the changing parameter to a temp variable and call xgifb_reg_and_or only from one location. -> Easier to read, easier to understand (especially wrt the line breaks) (For the if condition we don't need the Temp variable, so we can use the value directly).
