The only 'unlocking' step is just pressing the home button.
It's not (nor has ever) pocket dialed anyone because you still have to press the home button just for the screen to turn on, then it would have to hit a specific app, then hit a contact/recent number, then go into that info screen and hit the number to start dialing.
No, that's not the only unlocking step as you still have to swipe to unlock. It serves an important purpose as the home button can be accidentally pressed even while in pocket. You'd be surprised how often pocket dialing happens when people don't sleep their devices before pocketing them.
For many of us, TouchID is as fast or faster than swipe to unlock.
