I believe they mean an option when running auto-import to automatically run Rename, Move, & Copy on the imported files without user intervention. iTunes also did this kind of thing back in the day on anything you imported, it'd rename files and add things like track number and disc number.
Basically how it could work is; auto-import finds new files and imports them into MC, the Rename, Move, & Copy tool is then silently used in the background setup to whatever the user wants it to do and executes it and then MC updates itself to the changes of the newly imported files.
I admit, that would come in handy. Automating import to automatically use Rename, Move, & Copy based on my default rules then automatically use update tags from library would be a major time saver. It'd be like scripting import and how it should do it if you have a preference so it saves time.
