As stated by unilevel MLM plan, it supports one line of distributors so that everyone under you is a frontline. There isn't any spillover in the unilevel plan so every distributor sponsored will be placed in the frontline of the distributor who sponsored them. As the commissions are set based on the number of people added on your frontline, you will get more commission by pushing your frontline people to add more people on their front line.
