|Aside from the question of examples or not examples, I offer the following suggestion… The wording is quite awkward and difficult to parse. So much so, I am not 100% certain of the intent.|

Providing IP number resources to third party devices, including addresses for point-to-point links or addresses provided on an impermanent basis, for use on a network managed and operated by the assignment holder shall not be considered a sub-assignment.
Providing IP number resources for permanent or semi-permanent connectivity, such as broadband services is still considered a sub-assignment.
