Handy for anyone updating a site from static h to dynamic php pages; requests to the old pages are automatically rewritten to the new urls. No one notices a thing, visitors and search engines can access the content either way. Leave the rule in; as an added bonus, this enables the authors to easily split php code and its included html structures into two separate files, a nice idea; makes editing and updating a breeze. The [NC] part at the end means "No Case", or "case-insensitive"; more on the switches, later.
