I've asked the same question before. It seems the reason is to provide rotation, but I've never seen any evidence in my engine that the valves rotate. Every valve stem has marks where the swivel foot has rubbed, but they're confined to one side of the valve stem with no evidence of rotation. I don't think there's enough friction between the face of the ball and the stem to induce rotation.
After reading about some car people's experience with the ball getting pounded through the elephant foot adjuster, I've decided to give the expensive Porsche adjusters a try. Haven't yet received them, though.

Here's a thread comparing some of the elephant foot adjusters:

There have been some adjuster failures mentioned on the forum. The only one I'm aware of that's been well documented involved incorrect installation. Others have mentioned failures where they were believed to be installed correctly, so I think this might be an area where either better parts, more frequent replacement, or more careful installation is warranted. Curious if anyone has simply installed stock adjusters with no moving parts to wear out.
