That is not correct, it's a typo or a mistake. If you click on withdrawal on Binance, the fee would be zero dollars, but immediately you paste your address, the fee would be indicated below, just like in the below image. In deposit, legacy and segwit addresses are separated, but both are not separated if you want to withdraw and the withdrawal fee are the same.
Nice try, thanks!Anyway, checking with Wayback Machine, they reduced withdrawal fees for Bitcoin. Likely they only changed since 2020.

Binance do not separate legacy and segwit withdrawal fee, even if it is separated, I expect segwit address withdrawal fee to be cheaper, not other way.
Logically it should be like that but if exchanges, exclusively Binance, take a couple of years to integrate Native Segwit to their exchanges, everything is possible.
