The user/robot interprets the page results as the genuine page it requested..even tho it's been redirected to another page.
(IE..the user/robot is looking for "pagename.htm", however that page no longer actually exists on the website, the mod rewrite can redirect the user/robot to another page without actually telling the user/robot that it was redirected, so it's not really looking at the page it requested but it doesn't really know the difference. The user/robot receives the same OK codes it would have received if it went to the originaly named page...)
Don't waste time worrying about it, just remove the redirect and continue looking for any other problems, such as multiple subdomains resolving to the same pages, i.e. more that just domain.com and www.domain.com resolving to the same content.
After any change to robots.txt, and even just periodically, it's a good idea to validate [searchengineworld.com] it.
