if 2 major alliances decided to pick the same quadrent, that is easily 480 people, logistically it's not all that hard for it to work out like that, hell if we wanted to, we could all as a server decide to go one quadrent, there is nothing stopping us from doing that (other then it not working realistically)
Also you are aware that the differences between a bot/multier and an actual player are extremely minor in looking at them as an account right?
Alliances can choose to push someone if they want, and it's hard to tell an actual alliance doing that apart from botters.
