I'm not really sure what issue you are fixing here.
Is it the redundant braces around the nested if () statement?
If so, the flow before and after the patch is different. Is this intentional?

return".

The patch only removes the else clause.

Yes. The patch improves readability by removing the outermost context, reducing
the nested conditional complexity.
