The reason is you are using a faster touchid iphone. You cant expect a feature always works in a way u wish.
It works in that way for a few generation...

I see that some people don't understand what's going on.
I DON'T have an iPhone 6. My Touch ID is so fast that by the time I click the home button (with the screen off) and lift my finger as quickly as possible, it still takes me home.
What SHOULD happen is this: Click the home button while screen is off. Touch ID unlocks the iPhone. I then interact with the notifications, then I press the home button to actually go to my home screen.
THEN, if I wanted the iPhone 5s/6 way of doing things, I could use the option "Rest Finger to Open" which would then let me press the home button once, rest my finger there, and the iPhone will go to the home screen automatically.
However, with Rest Finger to Open ON or OFF, I get the same exact results, which defeats the purpose of having that option.
