"5 degrees of nose-down movement" is an official statement by Boeing. It wasn't from the media. I think that clearly implies the system is designed to create nose-down movement.

I see, thank you for those examples.

We typically see it described as preventing a stall, I guess that's why it seems odd to see it working when the plane is in a dive. In this case I suppose it...
