it means things will only get worse from this point on. I agree that it can be meant two ways...either it's going to get worse and go downhill or that you've made it over the hard part (the obstacle or hill) and it's going to be smooth and downhill  from here on.F you are an optimist then it is a good thing. If you are a pessimist then it is a bad thing. It most often is a double entendre, encompassing a hint of caution within the concept of coasting. Hard work will take you climbing up a hill, and once you reach the peak, gravity will slide you down the other side.
French also used this word for hillside, slope, which led to verb meaning sled downhill, first attested 1775 in American English. Expression the coast is clear (16c.) is an image of landing on a shore unguarded by enemies. v. late 14c., to skirt, to go around the sides, to go along the border of something (as a ship does the coastline), from Anglo-French costien, from the French source of coast (n.). The meaning sled downhill, first attested 1775 in American English, is a separate borrowing.
