They don't act intelligent, they are obviously mindless Titans. This is not the first time Zeke transforms people into mindless Titans and then controls them and uses them as his disposable army (someone remembers Ragako and the scene of Mike getting eaten?). So I don't know where is the confusion. Mindless Titans = potential targets for the Coordinate.
