inconsistency of post timeline data on profile

I noticed the timeline posts on a user's profile are cached/stored separately to the updated post?

i.e. https://laracasts.com/@Braunson

I posted an initial response to someone with a broken link (I mis-formatted it) but edited the post and fixed it. When I go to my profile, I still see the previous post.

Perhaps it's queued and hasn't updated but just an inconsistency of same-data I noticed.
