Answer
It can lead to bugs, as the inner variable hides the outer one.
Using the same name in nested blocks means the inner variable will mask the outer. In a product pricing loop, if you declare 'discount' inside an if block, it might override another 'discount' variable, leading to incorrect pricing logic.
