This thread reminds me of US and EU passport users who thought they could use airside TWOV to do cheap trips to/from China only to find out that a roundtrip ticket to and from China even when heading back on the same plane as the one coming in -- and having no need to even go landside for any reason -- wasn't going to fly with the airline and not necessarily reliably even with the Chinese personnel manning airside TWOV stations.

If you're going to try to game around a restriction, then note there are risks of facing an unwelcome situation when the game is being done on a basis that is short of adequate information and experience to avoid an unwelcome surprise on the intended day of travel.
