Why do my badges change from beta to meta, but not my rep?

Question

I see at the top of the meta page that my rep doesn't change when I switch views from the main beta site to its meta site. But the badges do change. Is there a reason why the badges are not made to "stick" to me like the rep, between beta and meta?

Answer 1

There are different badges for main and meta, but rep is for main only.
