It's just odd that they wouldn't mention it. Before the rework, the ult would still hit you so long as the animation started, but that doesn't work anymore for some reason. And Garen's is odd too. You can dodge it by making him lose vision of you as the animation starts, but it will still hit you even if you flash out of range, so long as he can still see you. Cho's ult can't be dodged in either case. It's just a very strange inconsistency.
Like Lord Boltrix said, Garen summons a giant sword out of the sky. If he can't see you, he doesn't know where to summon the sword. If you flash away, it doesn't matter cause the orbital laser sword is locked on your coordinates. :)
