The original file used this indentation quite a lot. Took me a bit to get used to, but now I think it helps because a nested block can be aligned with the outer one. This identical horizontal alignment emphasizes that the nested block is an emancipated part of the outer one (e.g., possibly disabled if enclosed by ```version ()``` or using another calling convention) - imho it avoids creating an unintuitive and unlogical hierarchy and is particularly useful for code like this.
