The behavior has changed in 8.0 or will change soon in an incremental update to 8.0.
Previously (and maybe in 8.0) if you had the brake on during an AEB event it wouldn't trigger
What's planned (and maybe in 8.0) is if you have the brake on it will amplify the braking.
From the blog post
In both versions hitting the throttle disengages AEB.
- Automatic braking will now amplify user braking in emergencies
Interesting development ... will AEB now bring the car to a stop or just reduce the speed by 25mph?
