How to get a 100% win record in random 2v2

But does the game remember if you took the placement match? I mean like if you invite the player you will lose 2 placement matches. If you get paired with him a month later, you will lose 2 more. If it happens again with the same player 2 months later and lose 2 times again, will the game remember the 4 previous matches and put you in fluffy with that player?
