We could see how George had been sarcastic(as much as John was, but with finer humor) about that lawsuit with "This Song" promo doing a parody of the judgement on the court ridicularizing that session. That was hilarious, but I think that song really "came unknowingly" to him as he sang. He didn't have bad intention to "plagiarize" consciously "He's So Fine" song, that's what I believe.
Peace.
