In 2 games at once?

So I was in a match and It was going well. All of a sudden everyone freezes and it says reconnecting, I didn't wanna just sit there and reconnect so I disconnected from the match really quick. I try to reconnect and my client doesn't give me the option. I can start another match but i'm not sure if i'm going to get marked as Leaving game or AFK. I can't reconnect and the game is still active because I see it on OP.GG. If I don't get reported for AFK and get punished for that I guess it's fine, but still I don't understand how that happened. Overall question is, will it go down as a game where I'm the leaver?
