This has come up before on this forum, and I posted this about it the last time.

This is the official explanation: "The flag consists of four colors: red, white, green, and black, inspired by the poetic verse of Safi al-Din al-Hilli, a 14th century warrior poet: 'Our actions are bright, our battlefields are dark, our lands are green, and our swords are red with the blood of our enemies.'"

I just don't think there's anything to this connection the man in the video is attempting to make.
