Doesn't change the point though.
Indeed not.
Your point about examining arrivals and airways was right on the mark.
The sole reason for picking the nit was to provide some context or "big picture" on how IAPs are constructed.
While it shouldn't be necessary for a pilot to be a procedures designer, an awareness of the segments of an approach sometimes helps answer questions about IFR navigation --e.g., when is it OK to fly straight-in, when is it necessary to fly a course reversal pattern, etc.
