If I am reading your question and images correctly, in image 1 (left), you are getting the total events of "level_end" where level status is win OR level status is wine and >0. In practical terms, that will be "level status is win" since the OR makes the broader filter cover the narrower filter. In your second example (on the right), Metric A will return the same as your first example, since it's just level_end where level status is win. But you will also get a second result with Metric B which is just the narrower case of level_end where level status is win and hint used is greater 0.
