Why is Gendo Ikari called Shinji by Kaworu in "The End of Evangelion"?


In the recent Italian re-dub of _The End of Evangelion_ , just before Gendo

> is seen eaten by the EVA-01 and dying,

Kaworu called him Shinji.

However, this is missing in the English version.

Why does Kaworu call Gendo as Shinji?
