It's called the Oxford comma usage, and yes, you're right about that. However, many writers prefer to remove the comma before the word "and" in a list of three or more because it is considered ambiguous to use too many commas when such is not needed. After all, there is such a thing as using too many commas in sentences if you get my drift.
