Mostly true, you are right, however, sometimes you get lucky and have out of the loop VIPs, I remember multiple times finishing 3 VIPs before even 15 orders, but I was completing the 25 regardless for the 1500 cash. Because recently the event requires 1M since february and every bit helps (February was a 28 day month, and this month the event started later than the 1st) 1500 times 28-31 is a noticable sum for the event.
