Hi Shai,
Running in closed loop implies the BEMF or current is being monitored. When the motor is running properly, the BEMF provides a signal for commutating. The signal can be used to determine the motor speed.
If the motor stalls, the BEMF signal will collapse. The motor will no longer run in closed loop, and will have to go through the startup routine.
A quick web search shows that most ESC are closed loop.
