Maybe you're looking at the "Discover" tab and not the default one which is called "Following".

One scenario where chronology is confusing is when a reply to an earlier tweet takes its chronological place in the timeline but also includes the earlier tweet for context.

I am looking at the tab called Following. I even turned off quotes, replies and mentions. It still shows only 3 days (yesterday it was 4 days) of posts by followers followed by random crap.
