Some of what you've written is a little vague -- for example, you talk
about "the host computer," and it's not clear whether you mean the SSH
client or server (they are both "hosts"). However, two things suggest you
have a basic misunderstanding;

In SSH forwarding, the SSH *client* is running an X server (i.e. has an X
display). The X forwarding allows X clients running on the SSH server to
use the SSH client's display. The "xauth generate" command establishes a
new X security key for use with this session, and so naturally talks to
the X server to accomplish that.
