Don't worry about it at all. If anyone questions later, simply explaining that CX protected you on TG due to a misconnect will be enough.
Sorry, but this leaves OP with nothing in the event that things don't go as you've laid them out here. Reminds me of an incident many years ago when I was a computer geek. My dataphone rang; and it was someone who had received a shutoff notice from the electric company (apparently the numbers were similar). I listened to his story, then told him that it must have been a computer glitch and not to worry about it.
Never hurts to call and confirm. At the very least, that 1) puts a note in your record about what happened, 2) puts CX on official notice that you're not going to be on the ticketed flight but still not a noshow, 3) gives you something to go back to in the event that things don't go exactly as planned. If OP follows your advice,
JAXBA, s/he is showing much more faith in the system than I would have, especially when the possible consequence is the cancellation of the rest of a RTW itinerary.
