Hi Stalin - Thanks for the post.
These are two separate settings. The options you find under the additional info section of a user's profile are associated with the 'Show Me How' incontext help menu. Based on the training role selected a different set of options will be presented to the user in the 'Show Me How' dropdown menu. Special Permissions on the other hand grant the user additional access within the software e.g. a user with Financial Permissions will have visibility to project financials.
