I would not read too much into it, I know it's not what you want to hear.
They still have feelings for you and are concerned for your welfare, its early stages and they are still in their fog. You have to remember they think they are in control and you are pathetic, in their eyes any way, that's why it's important to GAL and show them you don't need their sympathy or support, you can get along without them.
My wife still dose this "are you alright" look out for this look out for that and texting things she think might help. It all comes down to them wanting to be in control, "I still want to be friends" It's what THEY want, not what WE want.
Just be civil when you reply to him, don't show any signs of weakness IE pursuing ect be friendly but not too friendly.
They just want it all, their OW and you waiting if it all goes wrong, you deserve better than that.
