Why would an ex make a fake account to talk over just reaching out directly?

My ex from 1.5 years ago made a fake account and messaged me, asking how I was doing. He then said he’d like to take me out sometime. I could see that the account was connected to his phone number, so I knew it was him.

My question is why wouldn’t he just reach out to me directly? Why go through the trouble of creating a fake account?

He’s the one who blocked me, so it’s not like I ever closed the door on him contacting me
