My speculation for a little while based on my experience with the low-level behavior of similar hardware is that the S3 has some combination of a hardware limitation and/or a driver performance problem which limits how much data they can pump through a single cable card socket - my speculation is that they can pump a full HD stream through each socket, but might not be able to push 2*HD through a single socket.
Complicating matters further, it could well be the case that they can get two typical bit rate HD streams through the socket but two maximum-bit-rate streams will choke it, so they're disabling multi-stream functionality on the S3 because they can't predict when that might happen or prevent it...
Again, this is total speculation. I'm probably completely wrong about this.
