I think a more reasonable comparison is 4 lines of code you have to think hard to decipher but is correct, vs 40 lines of code that has a bunch of bugs and edge cases and is just as jibberish but 10x more code to decipher. Shorter solutions often encode the authors insight from thinking about the problem, and longer solutions encode are more of a history of the path an author took while just hammering on it without any particular insight until it worked good enough.
