MacBook Pro 13" 2018 Black Screen issue

Hi, I recently bought the new MacBook Pro 2018 13" with Touch Bar and i5 processor/8gb/256gb. Today I noticed that when I slide the brightness to zero (I slide the Touch Bar control of brightness all the way down) the screen blacks out while the computer is still running.

I do not know if this is an intended feature, but I assume it's some kind of software issue.

PS. I run the latest version of Mojave
