I don’t think it does. ATProto is merely “managed storage for apps” by Bluesky and it’s quite opposing to POSSE - You rely on third parties entirely, not just for hosting but also access and moderation to your own content.
What you can and can’t do with your own content is also limited and managed by someone else. The entire premise that you can move your posts history etc, while technically true, is not compatible with the web (e.g. support for things like redirects, canonical urls being handled currently etc is again all outside of your control and a not a goal of Bluesky).
ATProto is in many ways like the custom HTML extensions Microsoft had in Internet Explorer to “make better user experience”.
For me one of the main points of POSSE is resilience. If the VCs behind Bluesky got tired of it tomorrow, all that would die is some links to your website. Your posts and content, RSS subscribers, people who linked or bookmarked your website etc - remain unaffected.
