Nope. In the reverse cycle, your metering device will be regulating the superheat the same way as before. If you're using a capillary tube, it will allow the same flow in the reverse direction. I myself love TXV metering devices. However, if you employ tx valves, there needs to be one for each heat exchanger. These either have internal check valves or need check valves plumbed across them, to bypass the txv for the heat exchanger being used as a condenser.
