Is the bold part "with differences in one defining the distinguishing qualities of the other" in the following passage grammatically correct? If correct, what's the meaning in detail?
---------- the following passage ------------
At the height of Baroque popularity, critics of its ostentatious grandeur began using the word Rococo to brand a lighter and more intimate form of decoration that was achieving prominence in and around France. By the mid-18th century, Rococo, in and of itself, had become an artistic movement combining architecture, painting, sculpture, and music. Contemporary art historians often categorize the two genres in comparison to each other, with differences in one defining the distinguishing qualities of the other.
