You can't even really look at the lock screen anymore when you
wake the phone by pressing the home
button — by the time the screen turns on, it's
already unlocked and transitioning to your home screen.
It also acts as a faster way to disable the feature if you have
already turned off Bixby Home (and the Bixby
button), as otherwise, you would need to use Bixby Voice to be able to go into Bixby Home so you can disable voice
wake - up.
