Bookworm,
That doesn't seem consistent with what you write above. It is, as you say, just an initial approach segment. Why is there a requirement to "keep your turns on the side of the hold"? After passing TGO inbound for the final time, the hold is irrelevant.
You will have explain where I was inconsistent. Regardless, ICAO says stay within the limits of the pattern. To me that means stay within the pattern as much as possible. In terms of airmanship, given that the hold is designed for 230kts, it is fairly obvious that a 737/A320 turning left would end up over or passing the airfield/approach area, that seems like an odd choice and even may take you outside of the buffer zone.
