There's a material difference between a buddy and someone who just happens to be in the water near you. You were diving with the latter.
Since you were drift diving in Coz. I assume that by turn the dive, you really mean end the dive, meaning begin the ascent to the surface. In either case, the turn or end the dive sign is a command not open to debate, and can only be considered a question if clearly signed as such.
Suggestions for the future: pick your buddies more carefully, and get agreed on communication, estimated dive time, and what you'll both do if one needs to terminate the dive early, meaning way before the estimated time.
Also, you could work on your air management somewhat (though it has no bearing on your buddy's faiulure in this case). One thing I do is get my buddy to agree that whoever is first to half tank let the other know. This way, both of know fairly early what our relative air consumption is and we can sometimes modify the dive accordingly. For example the lower on air buddy can focus more on the reef tops, while the long on air buddy can prowl the bottom. The difference of 5-10 feet of depth will help both divers to equalize their air use and get the most out of the dive.
With good communication and cooperation 2 mis-matched divers can each enjoy their dives to the fullest, but if they don't plan to work together they might as well admit they're really diving solo.
