The original claim was that Topics API doesn't use the whole browser history, and that sites inly get topics for that site.
Whereas the description clearly states that topics are derived from the entire browsing history, and they will get topics derived from the test of the history because while coarse, there are still a bunch of them.
A site with a narrow site like a site on fresh-water aquatic plants will probably only get a handful of topics. What will Amazon get? Or Google for that matter? Or a news site? Given that they are likely to "observe" every single topic?
The original discussion was comparing the Topics API to third party cookies.
The way that the Topics API works is that a website that could have set a third party cookie will instead be able to observe a topic, and will then be able to get that topic in the future.
The comment I responded to claimed that Topics API doesn't use the full history and that a site X won't get topics derived for site Y: https://news.ycombinator.com/item?id=37429447
