True enough. Its the man not the art.
I am not saying "I managed to do the nearly impossible task of successfully applying a core Aikido technique against a trained knife fighter, because I am a serious badass."
I am saying "If somebody like ME can pull of a kote gaeshi against one of these Kali guys, then true Aikido (anecdotal Aikido actually) is effective for disarming."
I succeeded because I managed to connect with my partner, take his balance and not give it back, and move way off the line. These are basic Aikido concepts that, if they exist in the system of Kali I trained in, they must be upper level concepts taught after some time training.
