I'm not tourney level, so my opinion might be wrong. But here's my observation.
For the Rachel match-up: Yea, Rachel can get out of the throw loop, but it uses some of her drive. And when that runs out, Rachel's offense gets crippled, AND Carl can now start his throw loop. So unless the Rachel is near death, the Carl will go for the throw loop always.
For AutonomousR: The biggest goal is so that when Noel drops her offense, the Carl player will use a Clap or make Nirvana move in some way. So when the Carl thinks it's safe to move Nirvana, R-1 does an air super to get a shit load of damage on her. If the robot's down, Carl is pretty much is done.
Hope that helps or is remotely right. ^_^
