Almost all modern torque based ECUs function similarly! You get a torque request, its converted to an aircharge request, which is converted to a MAP request, which becomes the driving force behind throttle/bypass/wastegate controls. Of course thats grossly simplified because they all do it slightly differently, but in this case, you're dead on.
The Actual Torque is estimated based on what it believes the aircharge to be using that table. This aircharge can be from a MAP sensor (via speed density), MAF sensor, or some combination. The Requested Torque is what is fed into the Tq to Aircharge table to get a desired aircharge. This then goes through an "inverse" speed density equation to get a desired MAP used to control the the necessary actuators.
