For the auto, because it's auto. With the Seamaster it's about them being different. And it is that simple. Helium just needs an avenue to escape when the pressure builds. Getting out via the crown will happen long before it pops the crystal. Saturation divers actually used this method. Remember this is not an issue in the water. It's an issue during decompression I n a dry environment in casual clothes.
The only divers that need this feature anyway are those divers, 99% commercial, that five deap enough and long enough where the air tanks are given a component of helium. They are given this to add pressure to their lungs. Being such a small partical, small amounts of helium can get into other places. Ie watch. As air pressure on the body begins to normalize in the watch in the decompression chamber, the helium has to escape, if any has penetrated.
For the Seamaster it's all marketing. I used to hate it, but...
