The way the matrix MLM plan works is simple. The default members are added to the first level and when new members are recruited, they spill over to the next level and even to other levels after that as the plan may permit. The most commonly used matrix MLM plans are 2*12, 3*9, 4*7, and 5*7. For example, when you choose a 4*7 matrix plan, you can recruit four members to the first level and the rest will spill over to later levels with a depth of seven levels.
