This is done to avoid crosstalk.
If, for example the up and down -links were on the same frequency, it would work much like a walkie-talkie, meaning only one person could send, and one receive, at any given point in time.
By giving each direction its own carrier wave, it allows both deviced to send and receive simultaneously, which greatly speeds communication.
