That took me way too long to figure out what you were talking about.

And we don't really need to see when someones typing considering the messages are fairly short and don't take a long time to write.

If I got that right, just imagine that in a tournament/betting room with more than 20 users. The whole visible chat area will consist of only these "typing signs".
While this isn't a necessary feature at all, I could see it being used for whispers/private chats. But yeah, don't think it should be used in public chats to avoid the scenario sir pointed out.
