To understand it, read "..on which..." as "whereas".

The two words actually mean different things, even though they are often used interchangeably by native English speakers. A society is a collection of individuals who have agreed to live together in order to make certain aspects of life easier. Those aspects might include security, housing, business, etc. In so doing, they agree to a certain set of rules. A culture is a group od characteristics that define a society of individuals. What are their religious, scientific, artistic, business, artistic, etc., habits and customs. I think as the world has become more multiple-cultural and people begin to recognize that either locally because of the inflow of many different people from many different societies, or globally due to the inter-connected nature of our Internet-based information rich world, Culture as opposed to Society has been used more and more to define a group of people.
