Ridiculously complicated Forum
the title seems redundant, and hardly anyone uses it. Plus the actual thread title is only editable by an admin. This is why you don't put any info there that might change. Say, like a price on something. God forbid you put in a typo, you can't fix those either.
The "response" title may serve an old tech purpose in a word search, it could get a higher ranking than the text in the messages.
For example, I do a search on the following phrase (with misspelling) and I get a direct hit in this thread.. Quotes around searches help.
"Alziemer checkup".
Back to your first question, the box around the thread number, just a user interface design that came along, probably, a long time ago.
Hang in there,
Marty KC
