Well, I don't know if it is confusing but it require explanation! Yes, you have to write 3 different mood for the same track, and procedural music is the fact a game "react" to the player action to make the music more energic, or add tension when you are close to enemies etc. It was used in Divinity OS2, Rainworld, No Man Sky, Sore, a Mickey game etc (A Monkey Island too, said Lumby!).
My advice is to create a simple theme, then switch it to minor, add some tension for the second track, then create the battle theme with more drums and using ideas from the 2 others tracks! But you are free to work as you want.
And have fun!
