Because if you record at 60FPS on you camera, when you play it back on your Cellphone it's going to play it back at 60FPS  (assuming you're playing back the high quality downloaded file and not streaming the 30FPS LRV file from the camera).  So you'll see the effect of a super sharp picture associated with a high frame rate (after all, your phone isn't going to know if you want a slow motion shot or a high frame rate shot).  So to get the slow motion effect, you have to open up your GoPro app, edit the file and halve the speed.  So that way if you've recorded a 10 second clip at 60FPS you'll end up with a 20 second clip at 30FPS = slow motion.
