These super short connections are actually one area I find that ET shines. As long as your plane is on the ground before the other flight closes its doors (which seems to never be right on time) then you'll make it. I've been the beneficiary of their service twice since the (former) NRT-HKG-ADD flight was perpetually late. But even times when I had plenty of time to connect, I always saw the ET staff meeting the plane to whisk people off on short connections, typically they'll either have a sign for your destination and/or be shouting it as you exit the plane.
