Interesting solution
Saw this while researching prices on Ebay this morning:
While the seller makes no note of the added bling, I suspect it's to stop the cradle from slipping backwards. I've never had this problem myself, but have heard others complain about it.
A bit too rich a price for a modded post (almost 140USD), but hey.

One of my Super Record posts would slip forward, not backward. The top part had been buffed shiny like the one in the picture. Another one I have was not buffed, and does not slip. I took the buffed one apart and sanded the places where the cradle contacts the top of the post with #220 grit emery cloth, then reassembled it without wiping the left-over emery grit from the post. It's an old machinists' and mechanics' trick. The grit gives some traction and discourages slipping. Seems to be working. Were some of the Super Record posts polished at the top by Campy, or is that a user modification?

I had one where the PO did a bunch of pinhead-sized dimplings all over the portion where the bottom cradle sits. The edges of the dimples were raised just that tiny bit which I assume helped with traction similar to the grit trick above.

Valve lapping compound between the contact surfaces will also do the trick quite handily.

Interesting indeed, but it seems like its overthinking, or even over engineering a problem. Never had slippage of an SR post rails' cradle personally, but the solution proposed by @nesteel seems the most logical and practical to me. My current SR post is the early model which DD mentions, above.

I have had one slip and roughening the cradle curved area did the trick tho I also have some gritty powder sold as a "grip medium" to help screwdriver tips stick to, and not strip, out screw heads. Probably nothing more than emery and a little rosin.
