In MILD, you're supposed to imagine the intended trigger of recognizing that you're dreaming happens the next time you're dreaming, just like prospective memory exercise targets like "the next time I see a red car I remember to check my state". Whether or not this is actually happening inside the brain when lucidity occurs, who knows.
My personal entirely unscientific theory is that lucidity is all about heightened (self) awareness perhaps together with subconscious expectation, and that MILD is one way to achieve it. People get better at lucidity over time because the neural pathways active during lucidity, and in being self-aware and checking your state get more and more established and take less and less effort to occur, and occur more frequently, over time.
