seeing other peoples masteries as your own

well i don't know if people notice or not but i was playing a few draft games and sometimes people left the game so while i waited i decided to look at that person profile until i found a game. i looked though the runes and masteries like normal but when i found a game i noticed instead of being able to see my normal masteries names they ended up being called the same way as the person who's masteries i just looked at were called, luckily in game i still had my keystones and all and it didn't affect how i played, but i just wanted to put it out there.
