Moto X Pure :: Does Flashlight Work With Phone Face Down?

So, even before i buy the phone, one of the highlights everyone make is:

"You can double-chop to turn the flash on or off. But if you activate the flashlight this way and set the phone face-down, the flashlight will almost immediately turn itself off."

Sounds awesome, so i tried it, double-chop works fine, but the flashlight dont turn itsel off when i put the phone face-down, and i waited a long time hoping the sensors have a delay, i tested in many surfaces and all the same.

It doens't seems to have a setting about this as the phone do it automatically..

So, that's it, i will have to accept it will never work on my phone? I already factory reset the phone after the update to MM, and a few days later.
