whatever maintains consistency, should be used
True.
the recommendation has the benefit of reducing source file size
And above all, it improves the readability by removing the unnecessary complexity in expressions, and it avoids further interrogations about such oddities.
Here the answer is obvious, the original writer has by mistake added an additional pair of parenthesis trough copy/paste.
The file is quite small, all the additional parenthesis should be removed, so the consistency will be kept.
