Reconfigure directly to the client:

"If the server does not have an address to which it can send the
Reconfigure message directly to the client, the server uses a Relay-reply
message (as described in section 20.3) to send the Reconfigure message to a
relay agent that will relay the message to the client."

So, my understanding was that this is the server-initiated message which is
NOT sent in response to relay's message. IMO, this invalidates the first
part of the bullet which says "A standards-complient DHCP server will never
send a message to relay other than in response to a message from a relay.."
