You can configure the bulbs in any way you would like. The only issue is that they use the same switch, so in order to turn off your overhead light you would need to physically flip the switch. This becomes a problem because the HUE light bulb in the pendant needs to be switched to the on position at all times in order for the HUE app / HUE bridge to be able to control that light. This can be remedied by either getting another HUE bulb or by taking the extra step of going into your app to turn off the pendant each time you want to turn on the overhead independently.
