I think you are confused about what you saw. You can chat with people on your friends list using this method and it appears as bubbles on the left side. Chat with your opponent is restricted to predetermined messages your hero will say. This is for the health of the community lol.
Hello everybody!
I was at gamescom yesterday, and I found what seemed to be a good new =)
chat with opponent was available in the version of the game they had,
by pressing ENTER a chatbox appeard on the middle of the screen and the chat was designed with bubbles on the left of screen,
don't know if my news is relevant but I thought you'll like it so I shared it with you =)
