That's how I read it. It should say it has no thrust.
A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.
For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.
