I don't think it's actually showing patrolled edits. I think Flow is just not rendering that part of the line.
As a user who combats vandalism by patrolling recent changes to lot of pages, I want to have a clean list of watched pages, where edits patrolled by other users do not show up, so that I can focus on reviewing only unpatrolled edits.
MediaWiki's patrol feature is enabled on ~70 WMF wikis, and allows this filtering of the watchlist by means of the user preference watchlisthidepatrolled, which I keep enabled all the time. However, this feature is broken on Flow talk pages: every single comment stays in the list forever!
On the following screenshot, the only patrolled changes which appear on Special:Watchlist are the ones on Flow pages.
