Correct. The actual aural carrier as received over the air is 5.5mhz lower (instead of 4.5mhz lower) than the picture carrier. That's what generates the 'intercarrier'. In superhet parlance, the intercarrier is the Intermediate Frequency or heterodyne between the two carriers, that difference signal appearing in the output of the V detector.
