There's nothing mysterious about it. All satellite channels are digital, so the uplink to the satellite is high-speed data. That makes HD and all the rest possible without losing clarity. The satellite regenerates the data signal, which cleans up any minor imperfections caused by the uplink. That maintains clarity on the downlink to you.
Internet and phone service via satellite is available, but the cost is very high and the data speed is limited. (As you suggested, the bandwidth on satellite links does have a practical limit.) For those reasons, it's only suitable for areas that don't have better options.
Satellite TV channels also have a practical limit. Most of them are held to 720p, although that's also true on cable systems.
