explanation: Update a feature module on your site. The update operation will produce a modified version of your feature module, which matches up with the configuration found in the database.
What happens with this modified code, depends on whether you do this with drush or with the web-based interface.
Using drush ("drush features-update [name]"), the modified code will replace your existing feature module in the filesystem.
The "recreate" button in the web-based administration interface is the equivalent to "update". However, the modified code will be provided for download as a .tar archive, instead of overwriting the existing feature module. It is up to the site builder to manually unzip and re-upload the modified module, replacing the original.
