It's an issue that you run into as long as you're forced to start with a yes/no answer. It's a problem forward-only LLMs have and diffusion models don't, and normal block diffusion is closer to forward LLMs than diffusion models. You could increase the block size to act more like a full diffusion model, but you would lose some of the benefits of block diffusion.
