Yes there are 2 radios in that AP.. The dot11radio 0 is the B/G radio and the dot11radio 0 is the A radio.  They operate on two different frequency ranges.

The A range is less crowded - wider spectrum with more channels, but the reach is not as far.
The B/G range is more crowded - bluetooth, wireless phones (not cell), etc.. use this range as well.  Only 3 non overlapping channels in the space, but it has farther reach than the A range.

B/G has been around a lot longer and traditionally when A came out it was used more for a bridging solution than a client solution.  Its really just been the past few years that laptop makers started even putting A wireless cards in laptops.  They have been doing the B/G for years so it is more prevalent.

Hope that helps.
