Interesting toolpath

I've done toolpaths like this a couple of times
but nothing as extreme as this

If you pause the vid at the 4 seconds mark - Back in my DO days, my mentor told me about a job he worked on for Rolls which was similar.
It was for sparking/edm a hole in a blade, and the "banana" electrode had to approach same way to "get up in there".
Long time ago now.... but I'm sure it was all run off hydraulic slides linked to a large custom rotary table, where the fixture/blade was mounted. Rotate the table and everything moved together to position the electrode.

That's called the G-spot tool path isn't it?
