Do Infinite SEO page/post settings get replicated as well?

Using New Blog Templates, I was wondering if Infinite SEO page or post meta settings such as SEO title and meta description gets copied as well?

If not, can there be a feature request so that all copied pages are SEO optimized?

Also, I had a side question: Do the SEO meta descriptions really do anything these days? I read that search engines don't really care about meta tags any more. However I see the importance of a good title.
