My 'Zetsu Assumption' is that the WZ's require someone to give instruction of some sort before performing a task, as no WZ has ever been shown doing something of its own accord, including Guruguru. These orders may be as simple as Obito's 'We have to help Rin' to something as complex as 'Hold Yamato within you so as to gain power and distract the Alliance.'
