Why do we give administrator rights for the user who is importing the applicatio

Why do we give administrator rights for the user who is importing the application?

means by following below steps:
1. Create the group on the source machine, and export it (in an application package) to the target machine prior to importing the main application.
2. Before exporting the application, add this group to all object role maps. Assign Administrator rights to this group.
3. Temporarily add the users (or user) who imports the application on the target machine to this group before performing an import.
4. After the import, remove users from the Application_Name_Administrators group, as needed.

What is the difference when we do without following this steps?...
