Yeah I was wondering why he would tell them to close there eyes if he was the only one going to be caught..
Also it could depend on How powerful your Tsukuyomi is. we all know that Itachi has the Strongest and most deadly Tsukuyomi out the bunch of the Uchihas so Itachi could consume 3 people instead of someone like Sasuke who has a inferior Tsukuyomi can only consume one person.
