Not true - I have just fixed it to work as it should.
I got Cortana to learn my voice by clicking on "Learn my voice" and reading out the 6 phrases. I rebooted as Cortana couldn't access the internet, and it now responds to "Hey Cortana" fine. I do not have to use keyboard or mouse at all.
I guess it was the responding "To anyone" that was the problem for me - it didn't understand my accent.
It should not be necessary to click on the microphone button if this setting is enabled.
