Good explanation. I've also used the technique for voice narration over music. I learned it as "ducking," but it's the same as sidechaining.
Essentially it's what you demonstrated, except the music would be the program material with the narration being the trigger, or key. This helps the narration be understood without the music getting in the way, without the need to turn the music down too much.
I sometimes wish TV programs would do this. Sometimes they do, but some times the music gets in the way of the dialog. They could use a good sidechain ducking.
