I'm posting the question here because it seems generic within IATA.
It is not end-on-end. That's a specific construct of fares where A-B + B-C are sold as a single itinerary with two fare components. It is also not a side trip as you are buying separate tickets.
The main thing to look as is if you are avoiding a minimum stay rule with the bookings, especially if returning to the point of origin. In your case the nested "return" is to LAX, not KUL, so no issues there.

This is a broad statement and not one I'm sure stands up to review.
