Both Fi and Fe can recreate feelings of others internally.
An Fe user will effortlessly do this and apply an extrinsic motivator (outside the person's self) as the cause of the feeling.
An Fi user requires an extra step, because Fi is usually contained within the user.
This step is called projection, and once it's done it applies an intrinsic motivator (within the person's self) as the cause of the feeling.
The accuracy of either's observation is only half correct, because causes of feelings are usually both objectively intrinsic and extrinsic in nature.
