  Yes, if the field is below sea level. They do exist!

  That's what the memo the airline company put out said about this. It's hard to say if it's a good thing or not, imagine an incorrect flight plan is entered but non 0, you could fly straight into another flight path or an obstacle, like a mountain.

  The preflight checklist covers setting this (and all other parameters) to correct values. Not only did the flight crew not do that, the statement by Emirates heavily suggests that instead of making people actually follow the preflight checklists (which cover many other safety-critical settings), they're relying entirely on the plane being left in the right state by the previous crew.
