I see that my explanation could have been better, but the mast crane could not lift that mast due to both weight and height.This implies that the crane hook needs to be higher than the mast which is not true.
As long as the hook and attachment to the mast is above the mast C of G it can be safely lifted/lowered.
The mast crane further away from the camera than the mast so height comparison is misleading.
But attaching the hook some meters above CG make hoisting safer and handling easier.
