Perhaps another dumb question...

I just notice that from http://www.satbeams.com/footprints?beam=5223 that

Astra 2A North
Astra 2A South
Astra 2B North
Astra 2B South
Astra 2C North
Astra 2C South
Astra 2D

All have exactly the same position in the sky, but different distribution patterns (on the map). I assume they're all the same satelite, just with different transmitters pointed at slightly different positions on Earth. Does this mean that once I align the satelite, that I typically could recieve channels from ALL of them at the same time (some may be stronger or weaker than others, depending on how the transmitter is pointed). But would I have access to ALL of the channels broadcast at once? Or do I have to reprogram my decoder box if I want to change from 2D to 2C (or something like that...)

Thanks for clearing the fog...
