Can anyone explain how the metal ring inside the seal seals against the pipe when the large nut is tightened??

If you notice when you get it, the seal will slide over the tube. When the gland nut is tightened to proper torque value that sleeve will compress around the tube end and bring the seal with it. The gland nut while being tightened will further compress the seal and encapsulate it. Over tighten and you may damage the seal (and tube).
I would mount the tube securing it at the pan first while putting the tube and seal into the oil pump inlet to ensure the tube and seal are positioned correctly for the gland nut to secure the seal properly.
Hopefully that explains it.
You might also want to use this product on the gland nut/oil pump threads. It will seal the threads and keep the nut from backing out with engine vibration.
