Interestingly the behavior is similar to what I have observed with Mouseflow recordings for organic Google+ and Facebook posts. The page is opened, the mouse never moves and the 'user' scrolls a couple of times. I wonder if these records could just be the regular reviews that Google and Facebook do; their visits do not show up on Google Analytics but Mouseflow is able to take recordings.
Isn't that how legitimate mobile or even laptop trackpad users look ? If I don't intend to click anywhere, the "mouse" cursor never moves - the page loads, I scroll, and go back by keyboard.
With a mouse, you get slight movement even while scrolling or pressing buttons, but with a trackpad or on a mobile device you don't, there's "mouse movement" even if you explicitly do some aiming before a click.
