When you register a stylesheet, you can specify the version number. But this is just appended to the end of the file name. WordPress will enqueue whichever version of that stylesheet was enqueued last, regardless of which is newer.
When you use be_register_latest_style() instead of wp_register_style(), it will check to see if that style has already been registered. If it has, it will compare the versions and use the latest version as the registered one.
This is useful for common stylesheets used by many themes and plugins, like Genericons.
