It's not an assumption, the fourth databook's description of Kotoamatsukami states there's really no need of eye contact for the use, the only necessary thing for the user must be a target in his range of vision. And Ninja Of War is right, it was needed in Itachi's case because Itachi himself programmed it to activate that way as a reaction to his own MS.
