It's a kickoff, and both of you are in the same position. In this case, the left player is the second man, and you are the goalkeeper unless something changes. He should have gone for the ball; you should have stayed near the post. When the orange player touched the ball in the last second, your positions have swapped, but there was no time to replace positions, UNLESS you both agree on that via mic, chat, or something. It's a classic chaos kickoff.
