Not necessarily. It can be a client on 2.4Ghz and an access point on 5Ghz. Even without that, if it has MIMO, then one of the antennas can be receiving 2.4Ghz while the other is sending (at least in theory, if the crosstalk between the antennas is low and the selectivity of the receiver is sufficient).
