On the phones I've owned with tap-to-wake, it wasn't a full unlock, just some level of the lock screen being illuminated. With my old Moto X, I could just wave my hand over the phone while it was laying next to me and a minimal version of the lock screen with clock and notifications would show up. On my current phone (Pixel) it does the same with a double tap: clock, notifications, nothing else. The phone doesn't unlock until I use the fingerprint reader or swipe my lock pattern.
