Digest: Difference between popular Posts and popular Topics

Hi,
I was wondering what the difference between popular Posts and Topics is in the weekly new email.
The Posts part seems to be identical with the weekly top page Discourse Meta
I also found this about its algo Improving the "Top" criteria
But how is the topics part different then?
Or is it just the continuation of the weekly top page below entry 5?

It feels a bit off that the first one is called top Posts although those all being Threads/Topics. Which causes a little confusion for me.

It is top posts, to see how it works, enter any topic with > 50 replies and click the “Summarize This Topic” button under the first post.

ふむ。私はこの週次メールについて話しています:


「人気の投稿」セクションは Discourse Meta と同一ですが、私の理解では、これは投稿ではなくトピックに関するものです。それらのトピックには50件以上の投稿はなく、メール内の投稿は常に最初のものです。

2番目のセクション「人気のトピック」は、最初のセクションの短縮版の続きでしょうか?そうでなければ、理解できません。

That is indeed a bit pointless. We’ll soon be redesigning the activity summary mail, in which popular topics will be the first to be highlighted. I think another change we should consider is changing Popular posts to Popular replies.
