I think the idea behind it is that on play 1 using the formation above we have 20, 80, 10, 15, 85, 45 eligible, however, on play 2 using a different formation we could have 20, 80 40, 88, 25, and 45 eligible. It's probably a system that uses the 2 QB's, a center, and 8 WR's utilizing quick throws and misdirection to counter the absence of an O-line. The defense thus has difficulty countering with a standard defense of 4 DL 3 LB and 4 DB. Even with the right defensive personel on the field they still have to match up with the eligible receivers from play to play.
