The two week sprint is for management. So that all the stakeholders only have to travel to "the pit" once every other week for a sprint review. It is vital that every team finishes the sprint at the exact same time. If teams are out of sync the stakeholders have to visit once a week or more. Given how important all these managers are to the organization, they need to be unloaded with trivial tasks such as playing with their phone during a sprint "review" (which is actually a demo).
