Loop Challenge: No. 5 Reversed List

I just wanna ask you guys why Codecademy admin doesn’t use negative index to compare the number[index] between lst1 & lst2. I found that it much more comprehensive.

Here is the code of Codecademy “if lst1[index] != lst2[len(lst2) - 1 - index]:”

Mine is “if lst1[index] != lst2[- 1 - index]:” I count lst2 from the final index [-1].

Is there something higher? Please advice. Thanks

Could be to keep things simple, so both indexes end up positive. It helps to have a link so we can look at the challenge in question.
