Yes. The issues are to what extent, if at all, does that extra step happen, and what does it actually achieve? Because if one looks at common ellipticals, the radius on the cut edge, if present at all, typically appears too small to participate or achieve anything.
The image Hepokatti posted is a marketing sketch, unfortunately and has some howlers which are misleading. The scale, especially shank, is hopelessly out, as is proportion. Drawing of the groove is below absolute limit spec for minimum groove depth, IIRC. Bottom clearance looks wrong. It seems to be drawn to convey a marketing concept, which I'm not even convinced is real.
Here's a markup of that image with actual front images of elliptical and FG styli to scale, and you'll see what I mean. In any event, I think this illustrates more realistic contact locations and proportions, and where the elliptical grind, and cut edge, is in relation to it. NB the overall groove depth is too shallow, I think, but that does not change the contact locations or fit :
