Attempted to simplify, hopefully I interpreted this correctly.

Suggested change

Again, hopefully interpreting correctly...

Suggested change

	The response to the request is a `AuthorizationResponse` JWT. If the callout is
	set to encrypt, the response will be encrypted for the server's nkey. The

	operator mode, it is possibly for the `AuthorizationResponse` to be issued by an
	a signing key for the auth account.
	The expected response to the request is an `AuthorizationResponse` JWT. If encryption
	is configured, the response must be encrypted by the server's configured xkey. The
	embedded JWT is expected to be issued by the nkey configured on the server.
	In operator mode, an alternate issuer to the JWT within `AuthorizationResponse` can
	be a signing key of the configured nkey.

My mental model of this is not fully formed and I think there is still some more room to clarify, but I am going to review the auth callout tests and then offer some more feedback.
