Whether or not the answer is wrong is irrelevant, currently, but the "this Pokemon" rule applies here. If a card refers to itself in the third person, with it's own name, then it can be substituted by "this Pokemon". Technically, "this Pokemon" was damaged during the last turn, so "this Pokemon" deals that much damage in return. Pidgeot would deal damage because it was damaged last turn regardless of what it looked like, or what it's name was.Yeah right.
Names really don't mean anything, they just make it more "realistic" by giving them names. Wth are you talking about?
