Yes it can remove people. It just depends on the background, etc it is sampling from. I tried one of my DS and his friends close together on the couch and it didn't do well with this one, but then I did this one of our trip to Colorado last spring break and removed my mom from the photo:
now the first edit seemed to be a little obvious on the cloning but I just selected part of it that stood out to me and selected content aware fill again and it made it better. Still less than 5 minutes from finding a photo to posting it here!
