implications of controlling ownership

A controlling ownership(more than 50% voting rights), however, does not necessarily mean that the entity has the power to govern the combined entity’s financial and operating policies so as to obtain benefits from its activities.

I came across this sentence in my Kaplan exam kit. And i find this slightly at odds with my understanding of control. If an entity has more than 50% voting rights than should not it straightway means that it has CONTROL over all financial and operating policy decisions of the entity?
