I installed openssh-server on two pc's. I can connect from both from the one to the other. So if openssh-server sends as well as receives ssh, why would you install the openssh-client, just to make sure nobody from another pc in the network can even try to log in to your pc?

You've answered your question yourself - why install openssh-server if you do not ever want to SSH into this machine - you would make your system less secure for no reason.
