Yes, but technically Fi doesn't involve its emotions in those of others either (it is a definitively subjective process and is rather split off in a sense). It rather evaluates the actions of others and acts on that evaluation, though the evaluation can definitely be flawed or motivated by an emotional stirring that acts out rashly.

The extraverted feeling type is a classical example of this, for he enjoys an excellent feeling rapport with his entourage, yet occasionally opinions of an incomparable tactlessness [p. 427] will just happen to him. These opinions have their source in his inferior and subconscious thinking, which is only partly subject to control and is insufficiently related to the object ; to a large extent, therefore, it can operate without consideration or responsibility.
So Fe does seek rapport with the emotions of others and in that sense is biased towards accepting the feelings around them, following the crowd and agreeing with it, while Fi seems to splinter off and form its own feelings. Basically, feeling (Fe or Fi) implies different forms of emotional bias, so I don't agree with you at all; Fe has very little in common with enneagram 4 or 5 because it tends toward following the crowd.
