seem like there is a missing support as the additional holes are actually used to fix the 4 supports instead of just 3?


The way I see - it's physics. Newton's First Law of Motion. You need only 3 (minimum) to achieve static equilibrium. Why you want to have another one when 3 already serve its purpose? To increase the cost of the product unnecessarily?
