Why does my ex ask about me to my friend?

me and my ex broke up a year ago because he lost interest and ended up lying to me the entire relationship and we ended the relationship badly

every time he sees or Text my friend he asks how I’m doing

why would he do this if he has blocked me and moved on and is currently in a relationship?
