More than one person can have the same semblence. My guess was that they have seen this type of semblence before but they didn't automatically recognize it in Pyrrha because she hid it. I'm sure Mercury could feel the magnetic pull in his boots, and I'm pretty sure if he realized what she was doing he could have realized he was being mind controlled.
