"but independent" vs "rather than independent"? 

My edit was reverted because editor Fat&Happy; deemed it to be my "analysis" presumably because I used the word "contrast" to describe the following inconsistency: Currently the page describes the system operating "independently within the government, but independent of it" [my bold] which is a quote from the Philadelphia Bank. However the Board of Governors of the system  describe it as "independent within the government" rather than "independent of government." [my bold]

If we must choose one definition then shouldn't it be that of the Board of Governors? If not then shouldn't both definitions be given? And if so, how is it wrong to use the word "contrast"?
