Question about how threads with large # of pages is displayed

[Buckeye]

On many threads that have large number of pages I sometimes find it difficult to select that last page because of the Deleted Post and Attachment Icons position.

Then I saw this one today that had the page # icons all at the bottom and went... hey I don't recall seeing that before, would be nice if all were like that.

I am not sure how all that is coded or why the two threads display different here.

The picture I show is just an example I saw today.
See the first post and how that is displayed, then compare to the last one.

Sorry if this has been brought up before, I just noticed the two different ways today, I know I am slow
