There is no officially designated definition for what constitutes a SAS. I've used an academic definition in my book (and flight test lectures) to help students understand what the various terms may mean.
But every manufacturer is free to call their system whatever they want.
This system combines the series and parallel actuators into one system (wish I knew exactly how they did this - must be pretty clever).
It's an object lesson to all of us to make sure you know what the terms mean and how the system operates.
