He wrote a long article and tagged a lot of people, some of whom are not my friends. It is a public post.
I opened the page of someone that is tagged in the same post and I could see the entry for it in his timeline, but in my own timeline, I can't see it.
Also, I can't see those who were tagged in the same post on my friend's timeline.

Go to your Activity page.
You can see the mentioned post there.
Next to that you can see options on right side.
Check whether that post is hidden from your timeline. If so, change it to "Allowed on timeline".
Hope this helps. :)
