Yes sir, sounds pretty typical. I wouldn't read too much into it or get worked up about it, just take it for what it is. The roller coaster doesn't shutdown when the papers are signed.
React however you deem appropriate. You can encourage the chatting or not. Remaining friendly would be good if you can pull it off w/o getting unrealistic about where it might go. I would encourage you to guard your heart.
In my sitch my X started reaching out a bit just after the D was final. Her wanting to "chat" with me most often coincided with times when she didn't have another steady guy in her life.
