Why is there a 20 posts review limit on the review queues?

I've searched the help pages and read the corresponding privilege page, but nothing even seems to mention that there's a limit to begin with, let alone the reason.

The only thing I found was this question: If you're not going to review and fix questions, don't use the review queue! Is it because of this question? Because people were OKing reviews when actually an action should have been taken?

Also, is this limit removed (or the cap increased) after a certain reputation, or are we all limited to 20?
