That does sound a more sensible interpretation to me. I know many in India (where vegetarian diets are prevalent) who eat meat occasionally when they suddenly crave for it, but are mostly inclined towards a veg diet. And they think of cannot eat non-veg foods for all three meals or even continuously every day for even a week unlike some others who can't do without meat in a meal. Perhaps bisexuality is also a spectrum rather than a 50-50 thing?
