Probably applies to new posts (new deletion actions) only. It happened with my comment in a recently deleted post (a draft to this one); I can’t find links to any entity related to that draft now. The old system was confusing in that people could continue a discussion even after the post was deleted, and its text was still accessible if you knew the link, but not author’s name. The new behavior is possibly a result of an attempt to deal with that issue.
