indirectly controlled by, controlling or under common control with such Party

[Galilom2002]

1.1 "Affiliate” of a Party shall mean and include any entity or association directly or indirectly controlled by, controlling or under common control with such Party.

Could you please explain to me the meaning of the above sentence, especially the second part "controlling or under common control with such Party."

[Our Tort System]

I think it's just a roundabout way of saying that:
"Affiliate" of a party is something that is under the party's control.
