English to Italian Law/Patents Law: Contract(s)

Il paragrafo in questione è uno dei termini di un contratto di commissione per agenzia madre (moda), ma la frase che non capisco è "worldwide is defined as USA and Europe running concurrently with or without any other territories that may be required".

"(b) any worldwide assignments (worldwide is defined as USA and Europe running concurrently with or without any other territories that may be required) (i.e., any campaign with respect to which the Client is entitled to use the Model's name, image, likeness, voice or other personal feature)".

Grazie per l'aiuto,
