Are you sending comments to indexer ?
Comments
Sure you're correct in assuming that the page is already indexed therefore it might confuse you as to why you would want to try and re-index an indexed page, but this is not what you would want to achieve, the reasoning for submitting them for indexing is so the page is re-crawled, re-cached and once this happens, your link will hold value, the page needs to be re-crawled/cached, for any beneficial value from your link.
So in my opinion, yes, it is very beneficial to index your comments. (not re-indexing, but resubmitting them for re-crawling / caching them).
