If I'm doing 75 in the middle lane along with traffic, and somebody behind me in the middle lane wants to do 95, I'm not obligated to move into the slow vehicle lane. They can pass on the left, in the passing lane. They are not entitled to pass on the right on the slow vehicle lane. You're right. This is not hard to comprehend.
