I assume the wifi and wimax are on different network interfaces?  If so,
then they are completely separate and the supplicant can handle as many
associations at a time as it has been given interfaces.

For example, you can definitely have two wifi adapters in your machine,
and run one supplicant that drives both interfaces.  Internally, both
interfaces are separate and both interfaces can maintain completely
different security associations at the same time.
