How does UE rotate actor with FRotator(pitch,yaw,roll)?

I haven’t found documentations about the following yet so I need your confirmation whether or not my understanding is correct.

I did several experiments and I found the following hypothesis:

A. UE rotates an actor relative to the actor local coordinate system which is LEFT handed coordinate system.
B. UE rotates the actor in the following order: first about Z (LEFT hand rule), second about Y (RIGHT hand rule), and about X (RIGHT hand rule).

That is the same conclusion I came to with my tests, as well.
