Answer
Using the same name in nested blocks can cause shadowing issues.
If a variable name like 'subtotal' is reused in nested blocks, it can cause shadowing, where the inner variable obscures the outer one. In an e-commerce scenario, this might lead to incorrect calculations for totals or discounts.
