[GAMEPLAY] ARAM Minion Bug?

I've noticed a couple of times in ARAM that the minions on blue side always spawn and move around the left-hand tower, compared to the red minions going straight through the middle. This might not make a big difference, but I thought I would post. I have seen this in multiple games now.

Theoretically, it could alter the single lane because red minions would always fighting on the blue team's side, since they got there earlier. In ARAM, it doesn't matter so much since everyone's barrelling down the lane smashing each other anyway. It might make a difference on Summoners Rift, but less on Howling Abyss.
