The default Enterprise Administrator role only has access to their own enterprise and does not have the Manage enterprises or Manage users of all enterprises privileges. So this user will only see the users of their enterprise. If this enterprise admin is a basic reseller, then they can log in to each of their enterprises in order to manage the users. 

A standard enterprise administrator with the additional Manage enterprises privilege will see their own enterprise in the left pane, and an edit button is displayed but the main purpose of this privilege level is to support resellers. A reseller administrator with the Manage enterprises privilege will be able to see all the enterprises in their scope. However, they will only be able to manage their own enterprise. 

A reseller user with an administration scope of more than one enterprise and the Manage enterprises and Manage users of all enterprises privileges can manage all the enterprises in their scope and the users of these enterprises too.
