This condition must also be true in Reco's scenario to send the forged 
packets to the reflectors.

How can the target tell the difference ? It will receive all packets 
from its internet router anyway.

"packets with a forged source address all coming from the same IP" does 
not make any sense. Packets do not "come from an IP", they just have a 
(possibly forged) source address wherever they come from.
