Frank's point is that when talking about engine efficiency, expansion ratio and compression ratio are two different concepts, both of which affect efficiency. (Expansion ratio as explained in the Wiki article you provided the link to is a different, largely unrelated, concept.) The Atkinson cycle engine is the classic example of an engine that is not symmetric in compression and expansion ratios.
