The dopplegangers imitating the other Pleiades also used their hands to demonstrate that they were dopplegangers. I believe this is simply a matter of convenience, as a Doppleganger hand differs dramatically enough to be clearly noticeable up close, but does not pose the same risk of more distant observers seeing anything amiss.

It is also possible that changing form involves a degree of fine motor control, which is greater in the hands.
