Not if it's an automated gate.
I just got back from Australia, and the passport gates there are automated facial recognition; they look kinda like the gates in a subway where you scan a travel card.
A reject heads over to the desk to get sorted. Everyone else keeps going through the automated gate.
And that's still going to be the case with facial recognition.
The only time saved is scanning a ticket vs scanning a face. And people are pretty much guaranteed not to lose their faces.
