Bruh it's just a theory that says Yuji has a technique that can do that because both Todo and choso REMEMBERED meeting Yuji before despite seeing him for the first time. In this fanfic the same thing happened, and this guy has a different soul than Yuji so he can have his own technique instead of relying on black flash.
If he can't access it then how is he gonna use it? Also, don't you remember when he said that, he had been training with his father for a year or two before he got his technique, if his technique was going to work even before being activated he would've adapted to the projection technique that old man uses, if he couldn't even do that then adapting to the world is too much of a stretch.
