Yes, I believe your understanding is basically correct.

I'm not convinced that it makes much sense to have a proxy involved in
connections to link-local addresses, particularly not a
globally-addressed proxy that might be on a different link to the host
making the original request. I suspect that most UAs would be better
off bypassing the proxy when the URL contains a link local address.
