To the other users it looks just like you normally would, no?

I thought the idea is that there is one bridge running per room. For example a discord room would be bridged to a matrix room by one running bridge. In discord, unless the API allows impersonating multiple users so that they appear as normal users in discord, the bridge couldn't mirror messages from all users in the matrix room and make them look like discord users. Unless I am misunderstanding how it works completely?

The slack one uses puppeting which is a 1-to-1 relationship to users. I expect most of them do this.
