BMW has two climate control systems, and those are the controls for the basic system. BMW only offers the advanced system on US e90 models (think this is true for all other US BMWs too), and I'm sure the same will be true for the f30. The advanced control panel offers dual temperature controls.
I think I prefer the e90's controls over the f30's. The older system used in the e90 had separate buttons for each vent location (floor/dash/defrost) while the newer system used in the f30 has a single button that you press repeatedly to cycle through all the vent combinations. Seems the former would be quicker and easier to use - fewer pushes and less need to look at the display. You also lose one possible combination (defrost+dash) in the new system. Granted, that's not a combo you often need but I have used it occasionally. On the other hand, the new system does allow the driver and passenger to set different vent combinations.
