Don't correct him with wrong information, his address is also Segwit. There are two types of Segwit addresses:
P2SH format - starts with 3
bech32 format - starts with bc1
Legacy addresses starting with 1
emphasizing the conditions with the SegWit address is to avoid Legacy and the reason for that I will leave for you to research.
Okay thank you for correcting me. I did not check the script. I searched his/her address and went through the transactions and checked the scripts and these are P2SH.
