Except this is the problem with looking at patches in Github, as opposed to as source code. Github shows you such an utterly minimal view of the overall flow of the code that it's impossible in a lot of cases to tell what the intent was or why - you don't even have function-level context for it. Compare to if you simply checked out main and the PR, and ran a meld across both directories - changes would be highlighted, but now you have to read the code in context.
