When I read the initial example I can understand it in the time taken to read the code.
With your example I had to think for about 1-2 min before it made sense. If the codebase is full of clever stuff then I have to spend hours understanding all of the clever things before I can make changes. If everything is simple then it's easy to change.
If you want to see where overengineering leads you then take a look at this project. https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpris...
It is satire but I have absolutely worked in places that write code like that.
Good programmers know that it's 10x times harder to read code than write it, so they deliberately keep it simple so that they can read it later.
