In Greek the direct and indirect pronoun are not the same like in English.
For example in English we say : I met him and I talked to him.
Both direct and indirect object are the same. If you translate the same sentence to Greek:
Τον συνάντησα και του μίλησα
Here the “Τον” is the direct object and the “του” is the indirect. I will give you a second example to understand it better:
Σε ικετεύω μην το κάνεις! - I beg you don’t do it! Whom do I beg? -> you.
Σου έφερα φαγητό να φας.- I brought you food to eat. To whom I brought? ->to you
