Interesting ideas, but maybe for the more advanced player. Basic stuff not covered well, particularly the first few lines that cover the first and most important line, the Fried Liver Attack. Black should know that and immediate d5 is required, and then after the ed pawn capture temporarily obstructing the Bishop attack on f2, the traditional and still good line is to play Na5 eliminating that bishop. Recent moves Nd4 and b5 are interesting, too for those bored playing the traditional line. The line described in this video is probably not as simple and good as these known and good solutions. Although I'm posting this 9 mths after the video was published, I'm mystified why the standard and traditional line which has been played for hundreds of years wasn't mentioned.
I think you are confusing move orders. Nd4 is not possible like it is in the straight up Italian two knights 4.ng5 stuff. Unless you mean you wanted him to cover the 2 Knights in the Italian also, but it's possible that black would play an entirely different move order, such as 3...Bc5
