The so-called heterotrophic autotrophy is based on individuals. Eat the meat on your legs every day, and you can't say that you are an autotroph. If you eat the meat on your legs every day, you are finished. Consumers can't produce, so consumers are different creatures, and producers are autotrophs. Heterotrophs must be a consumer, and autotrophs must be producers.

Special case: Mistletoe is both a producer and a consumer, so it can be heterotrophs or an autotrophic organism.
